GoJay

GoJay is a performant JSON encoder/decoder for Golang (currently the most performant, see benchmarks).

It has a simple API and doesn't use reflection. It relies on small interfaces to decode/encode structures and slices.

Gojay also comes with powerful stream decoding features and an even faster Unsafe API.

There is also a code generation tool to make usage easier and faster.

Why another JSON parser?

I looked at other fast decoder/encoder and realised it was mostly hardly readable static code generation or a lot of reflection, poor streaming features, and not so fast in the end.

Also, I wanted to build a decoder that could consume an io.Reader of line or comma delimited JSON, in a JIT way. To consume a flow of JSON objects from a TCP connection for example or from a standard output. Same way I wanted to build an encoder that could encode a flow of data to a io.Writer.

This is how GoJay aims to be a very fast, JIT stream parser with 0 reflection, low allocation with a friendly API.

Decoding

Decoding is done through two different API similar to standard encoding/json:

Example of basic stucture decoding with Unmarshal:

import "github.com/francoispqt/gojay"

type user struct {
    id int
    name string
    email string
}
// implement gojay.UnmarshalerJSONObject
func (u *user) UnmarshalJSONObject(dec *gojay.Decoder, key string) error {
    switch key {
    case "id":
        return dec.Int(&u.id)
    case "name":
        return dec.String(&u.name)
    case "email":
        return dec.String(&u.email)
    }
    return nil
}
func (u *user) NKeys() int {
    return 3
}

func main() {
    u := &user{}
    d := []byte(`{"id":1,"name":"gojay","email":"gojay@email.com"}`)
    err := gojay.UnmarshalJSONObject(d, u)
    if err != nil {
        log.Fatal(err)
    }
}

with Decode:

func main() {
    u := &user{}
    dec := gojay.NewDecoder(bytes.NewReader([]byte(`{"id":1,"name":"gojay","email":"gojay@email.com"}`)))
    err := dec.DecodeObject(d, u)
    if err != nil {
        log.Fatal(err)
    }
}
Unmarshal API

Unmarshal API decodes a []byte to a given pointer with a single function.

Behind the doors, Unmarshal API borrows a *gojay.Decoder resets its settings and decodes the data to the given pointer and releases the *gojay.Decoder to the pool when it finishes, whether it encounters an error or not.

If it cannot find the right Decoding strategy for the type of the given pointer, it returns an InvalidUnmarshalError. You can test the error returned by doing if ok := err.(InvalidUnmarshalError); ok {}.

Unmarshal API comes with three functions:

  • Unmarshal
func Unmarshal(data []byte, v interface{}) error
  • UnmarshalJSONObject
func UnmarshalJSONObject(data []byte, v gojay.UnmarshalerJSONObject) error
  • UnmarshalJSONArray
func UnmarshalJSONArray(data []byte, v gojay.UnmarshalerJSONArray) error
Decode API

Decode API decodes a []byte to a given pointer by creating or borrowing a *gojay.Decoder with an io.Reader and calling Decode methods.

Getting a *gojay.Decoder or Borrowing

You can either get a fresh *gojay.Decoder calling dec := gojay.NewDecoder(io.Reader) or borrow one from the pool by calling dec := gojay.BorrowDecoder(io.Reader).

After using a decoder, you can release it by calling dec.Release(). Beware, if you reuse the decoder after releasing it, it will panic with an error of type InvalidUsagePooledDecoderError. If you want to fully benefit from the pooling, you must release your decoders after using.

Example getting a fresh an releasing:

str := ""
dec := gojay.NewDecoder(strings.NewReader(`"test"`))
defer dec.Release()
if err := dec.Decode(&str); err != nil {
    log.Fatal(err)
}

Example borrowing a decoder and releasing:

str := ""
dec := gojay.BorrowDecoder(strings.NewReader(`"test"`))
defer dec.Release()
if err := dec.Decode(&str); err != nil {
    log.Fatal(err)
}

*gojay.Decoder has multiple methods to decode to specific types:

  • Decode
func (dec *gojay.Decoder) Decode(v interface{}) error
  • DecodeObject
func (dec *gojay.Decoder) DecodeObject(v gojay.UnmarshalerJSONObject) error
  • DecodeArray
func (dec *gojay.Decoder) DecodeArray(v gojay.UnmarshalerJSONArray) error
  • DecodeInt
func (dec *gojay.Decoder) DecodeInt(v *int) error
  • DecodeBool
func (dec *gojay.Decoder) DecodeBool(v *bool) error
  • DecodeString
func (dec *gojay.Decoder) DecodeString(v *string) error

All DecodeXxx methods are used to decode top level JSON values. If you are decoding keys or items of a JSON object or array, don't use the Decode methods.

Example:

reader := strings.NewReader(`"John Doe"`)
dec := NewDecoder(reader)

var str string
err := dec.DecodeString(&str)
if err != nil {
    log.Fatal(err)
}

fmt.Println(str) // John Doe
Structs and Maps
UnmarshalerJSONObject Interface

To unmarshal a JSON object to a structure, the structure must implement the UnmarshalerJSONObject interface:

type UnmarshalerJSONObject interface {
	UnmarshalJSONObject(*gojay.Decoder, string) error
	NKeys() int
}

UnmarshalJSONObject method takes two arguments, the first one is a pointer to the Decoder (*gojay.Decoder) and the second one is the string value of the current key being parsed. If the JSON data is not an object, the UnmarshalJSONObject method will never be called.

NKeys method must return the number of keys to Unmarshal in the JSON object or 0. If zero is returned, all keys will be parsed.

Example of implementation for a struct:

type user struct {
    id int
    name string
    email string
}
// implement UnmarshalerJSONObject
func (u *user) UnmarshalJSONObject(dec *gojay.Decoder, key string) error {
    switch key {
    case "id":
        return dec.Int(&u.id)
    case "name":
        return dec.String(&u.name)
    case "email":
        return dec.String(&u.email)
    }
    return nil
}
func (u *user) NKeys() int {
    return 3
}

Example of implementation for a map[string]string:

// define our custom map type implementing UnmarshalerJSONObject
type message map[string]string

// Implementing Unmarshaler
func (m message) UnmarshalJSONObject(dec *gojay.Decoder, k string) error {
	str := ""
	err := dec.String(&str)
	if err != nil {
		return err
	}
	m[k] = str
	return nil
}

// we return 0, it tells the Decoder to decode all keys
func (m message) NKeys() int {
	return 0
}
Arrays, Slices and Channels

To unmarshal a JSON object to a slice an array or a channel, it must implement the UnmarshalerJSONArray interface:

type UnmarshalerJSONArray interface {
	UnmarshalJSONArray(*gojay.Decoder) error
}

UnmarshalJSONArray method takes one argument, a pointer to the Decoder (*gojay.Decoder). If the JSON data is not an array, the Unmarshal method will never be called.

Example of implementation with a slice:

type testSlice []string
// implement UnmarshalerJSONArray
func (t *testSlice) UnmarshalJSONArray(dec *gojay.Decoder) error {
	str := ""
	if err := dec.String(&str); err != nil {
		return err
	}
	*t = append(*t, str)
	return nil
}

func main() {
	dec := gojay.BorrowDecoder(strings.NewReader(`["Tom", "Jim"]`))
	var slice testSlice
	err := dec.DecodeArray(&slice)
	if err != nil {
		log.Fatal(err)
	}
	fmt.Println(slice) // [Tom Jim]
	dec.Release()
}

Example of implementation with a channel:

type testChannel chan string
// implement UnmarshalerJSONArray
func (c testChannel) UnmarshalJSONArray(dec *gojay.Decoder) error {
	str := ""
	if err := dec.String(&str); err != nil {
		return err
	}
	c <- str
	return nil
}

func main() {
	dec := gojay.BorrowDecoder(strings.NewReader(`["Tom", "Jim"]`))
	c := make(testChannel, 2)
	err := dec.DecodeArray(c)
	if err != nil {
		log.Fatal(err)
	}
	for i := 0; i < 2; i++ {
		fmt.Println(<-c)
	}
	close(c)
	dec.Release()
}

Example of implementation with an array:

type testArray [3]string
// implement UnmarshalerJSONArray
func (a *testArray) UnmarshalJSONArray(dec *Decoder) error {
	var str string
	if err := dec.String(&str); err != nil {
		return err
	}
	a[dec.Index()] = str
	return nil
}

func main() {
	dec := gojay.BorrowDecoder(strings.NewReader(`["Tom", "Jim", "Bob"]`))
	var a testArray
	err := dec.DecodeArray(&a)
	fmt.Println(a) // [Tom Jim Bob]
	dec.Release()
}
Other types

To decode other types (string, int, int32, int64, uint32, uint64, float, booleans), you don't need to implement any interface.

Example of encoding strings:

func main() {
    json := []byte(`"Jay"`)
    var v string
    err := gojay.Unmarshal(json, &v)
    if err != nil {
        log.Fatal(err)
    }
    fmt.Println(v) // Jay
}
Decode values methods

When decoding a JSON object of a JSON array using UnmarshalerJSONObject or UnmarshalerJSONArray interface, the gojay.Decoder provides dozens of methods to Decode multiple types.

Non exhaustive list of methods available (to see all methods, check the godoc):

dec.Int
dec.Int8
dec.Int16
dec.Int32
dec.Int64
dec.Uint8
dec.Uint16
dec.Uint32
dec.Uint64
dec.String
dec.Time
dec.Bool
dec.SQLNullString
dec.SQLNullInt64

Encoding

Encoding is done through two different API similar to standard encoding/json:

Example of basic structure encoding with Marshal:

import "github.com/francoispqt/gojay"

type user struct {
	id    int
	name  string
	email string
}

// implement MarshalerJSONObject
func (u *user) MarshalJSONObject(enc *gojay.Encoder) {
	enc.IntKey("id", u.id)
	enc.StringKey("name", u.name)
	enc.StringKey("email", u.email)
}
func (u *user) IsNil() bool {
	return u == nil
}

func main() {
	u := &user{1, "gojay", "gojay@email.com"}
	b, err := gojay.MarshalJSONObject(u)
	if err != nil {
		log.Fatal(err)
	}
	fmt.Println(string(b)) // {"id":1,"name":"gojay","email":"gojay@email.com"}
}

with Encode:

func main() {
	u := &user{1, "gojay", "gojay@email.com"}
	b := strings.Builder{}
	enc := gojay.NewEncoder(&b)
	if err := enc.Encode(u); err != nil {
		log.Fatal(err)
	}
	fmt.Println(b.String()) // {"id":1,"name":"gojay","email":"gojay@email.com"}
}
Marshal API

Marshal API encodes a value to a JSON []byte with a single function.

Behind the doors, Marshal API borrows a *gojay.Encoder resets its settings and encodes the data to an internal byte buffer and releases the *gojay.Encoder to the pool when it finishes, whether it encounters an error or not.

If it cannot find the right Encoding strategy for the type of the given value, it returns an InvalidMarshalError. You can test the error returned by doing if ok := err.(InvalidMarshalError); ok {}.

Marshal API comes with three functions:

  • Marshal
func Marshal(v interface{}) ([]byte, error)
  • MarshalJSONObject
func MarshalJSONObject(v gojay.MarshalerJSONObject) ([]byte, error)
  • MarshalJSONArray
func MarshalJSONArray(v gojay.MarshalerJSONArray) ([]byte, error)
Encode API

Encode API decodes a value to JSON by creating or borrowing a *gojay.Encoder sending it to an io.Writer and calling Encode methods.

Getting a *gojay.Encoder or Borrowing

You can either get a fresh *gojay.Encoder calling enc := gojay.NewEncoder(io.Writer) or borrow one from the pool by calling enc := gojay.BorrowEncoder(io.Writer).

After using an encoder, you can release it by calling enc.Release(). Beware, if you reuse the encoder after releasing it, it will panic with an error of type InvalidUsagePooledEncoderError. If you want to fully benefit from the pooling, you must release your encoders after using.

Example getting a fresh encoder an releasing:

str := "test"
b := strings.Builder{}
enc := gojay.NewEncoder(&b)
defer enc.Release()
if err := enc.Encode(str); err != nil {
    log.Fatal(err)
}

Example borrowing an encoder and releasing:

str := "test"
b := strings.Builder{}
enc := gojay.BorrowEncoder(b)
defer enc.Release()
if err := enc.Encode(str); err != nil {
    log.Fatal(err)
}

*gojay.Encoder has multiple methods to encoder specific types to JSON:

  • Encode
func (enc *gojay.Encoder) Encode(v interface{}) error
  • EncodeObject
func (enc *gojay.Encoder) EncodeObject(v gojay.MarshalerJSONObject) error
  • EncodeArray
func (enc *gojay.Encoder) EncodeArray(v gojay.MarshalerJSONArray) error
  • EncodeInt
func (enc *gojay.Encoder) EncodeInt(n int) error
  • EncodeInt64
func (enc *gojay.Encoder) EncodeInt64(n int64) error
  • EncodeFloat
func (enc *gojay.Encoder) EncodeFloat(n float64) error
  • EncodeBool
func (enc *gojay.Encoder) EncodeBool(v bool) error
  • EncodeString
func (enc *gojay.Encoder) EncodeString(s string) error
Structs and Maps

To encode a structure, the structure must implement the MarshalerJSONObject interface:

type MarshalerJSONObject interface {
	MarshalJSONObject(enc *gojay.Encoder)
	IsNil() bool
}

MarshalJSONObject method takes one argument, a pointer to the Encoder (*gojay.Encoder). The method must add all the keys in the JSON Object by calling Decoder's methods.

IsNil method returns a boolean indicating if the interface underlying value is nil or not. It is used to safely ensure that the underlying value is not nil without using Reflection.

Example of implementation for a struct:

type user struct {
	id    int
	name  string
	email string
}

// implement MarshalerJSONObject
func (u *user) MarshalJSONObject(enc *gojay.Encoder) {
	enc.IntKey("id", u.id)
	enc.StringKey("name", u.name)
	enc.StringKey("email", u.email)
}
func (u *user) IsNil() bool {
	return u == nil
}

Example of implementation for a map[string]string:

// define our custom map type implementing MarshalerJSONObject
type message map[string]string

// Implementing Marshaler
func (m message) MarshalJSONObject(enc *gojay.Encoder) {
	for k, v := range m {
		enc.StringKey(k, v)
	}
}

func (m message) IsNil() bool {
	return m == nil
}
Arrays and Slices

To encode an array or a slice, the slice/array must implement the MarshalerJSONArray interface:

type MarshalerJSONArray interface {
	MarshalJSONArray(enc *gojay.Encoder)
	IsNil() bool
}

MarshalJSONArray method takes one argument, a pointer to the Encoder (*gojay.Encoder). The method must add all element in the JSON Array by calling Decoder's methods.

IsNil method returns a boolean indicating if the interface underlying value is nil(empty) or not. It is used to safely ensure that the underlying value is not nil without using Reflection and also to in OmitEmpty feature.

Example of implementation:

type users []*user
// implement MarshalerJSONArray
func (u *users) MarshalJSONArray(enc *gojay.Encoder) {
	for _, e := range u {
		enc.Object(e)
	}
}
func (u *users) IsNil() bool {
	return len(u) == 0
}
Other types

To encode other types (string, int, float, booleans), you don't need to implement any interface.

Example of encoding strings:

func main() {
	name := "Jay"
	b, err := gojay.Marshal(name)
	if err != nil {
		log.Fatal(err)
	}
	fmt.Println(string(b)) // "Jay"
}

Stream API

Stream Decoding

GoJay ships with a powerful stream decoder.

It allows to read continuously from an io.Reader stream and do JIT decoding writing unmarshalled JSON to a channel to allow async consuming.

When using the Stream API, the Decoder implements context.Context to provide graceful cancellation.

To decode a stream of JSON, you must call gojay.Stream.DecodeStream and pass it a UnmarshalerStream implementation.

type UnmarshalerStream interface {
	UnmarshalStream(*StreamDecoder) error
}

Example of implementation of stream reading from a WebSocket connection:

// implement UnmarshalerStream
type ChannelStream chan *user

func (c ChannelStream) UnmarshalStream(dec *gojay.StreamDecoder) error {
	u := &user{}
	if err := dec.Object(u); err != nil {
		return err
	}
	c <- u
	return nil
}

func main() {
	// get our websocket connection
	origin := "http://localhost/"
	url := "ws://localhost:12345/ws"
	ws, err := websocket.Dial(url, "", origin)
	if err != nil {
		log.Fatal(err)
	}
	// create our channel which will receive our objects
	streamChan := ChannelStream(make(chan *user))
	// borrow a decoder
	dec := gojay.Stream.BorrowDecoder(ws)
	// start decoding, it will block until a JSON message is decoded from the WebSocket
	// or until Done channel is closed
	go dec.DecodeStream(streamChan)
	for {
		select {
		case v := <-streamChan:
			// Got something from my websocket!
			log.Println(v)
		case <-dec.Done():
			log.Println("finished reading from WebSocket")
			os.Exit(0)
		}
	}
}
Stream Encoding

GoJay ships with a powerful stream encoder part of the Stream API.

It allows to write continuously to an io.Writer and do JIT encoding of data fed to a channel to allow async consuming. You can set multiple consumers on the channel to be as performant as possible. Consumers are non blocking and are scheduled individually in their own go routine.

When using the Stream API, the Encoder implements context.Context to provide graceful cancellation.

To encode a stream of data, you must call EncodeStream and pass it a MarshalerStream implementation.

type MarshalerStream interface {
	MarshalStream(enc *gojay.StreamEncoder)
}

Example of implementation of stream writing to a WebSocket:

// Our structure which will be pushed to our stream
type user struct {
	id    int
	name  string
	email string
}

func (u *user) MarshalJSONObject(enc *gojay.Encoder) {
	enc.IntKey("id", u.id)
	enc.StringKey("name", u.name)
	enc.StringKey("email", u.email)
}
func (u *user) IsNil() bool {
	return u == nil
}

// Our MarshalerStream implementation
type StreamChan chan *user

func (s StreamChan) MarshalStream(enc *gojay.StreamEncoder) {
	select {
	case <-enc.Done():
		return
	case o := <-s:
		enc.Object(o)
	}
}

// Our main function
func main() {
	// get our websocket connection
	origin := "http://localhost/"
	url := "ws://localhost:12345/ws"
	ws, err := websocket.Dial(url, "", origin)
	if err != nil {
		log.Fatal(err)
	}
	// we borrow an encoder set stdout as the writer,
	// set the number of consumer to 10
	// and tell the encoder to separate each encoded element
	// added to the channel by a new line character
	enc := gojay.Stream.BorrowEncoder(ws).NConsumer(10).LineDelimited()
	// instantiate our MarshalerStream
	s := StreamChan(make(chan *user))
	// start the stream encoder
	// will block its goroutine until enc.Cancel(error) is called
	// or until something is written to the channel
	go enc.EncodeStream(s)
	// write to our MarshalerStream
	for i := 0; i < 1000; i++ {
		s <- &user{i, "username", "user@email.com"}
	}
	// Wait
	<-enc.Done()
}

Unsafe API

Unsafe API has the same functions than the regular API, it only has Unmarshal API for now. It is unsafe because it makes assumptions on the quality of the given JSON.

If you are not sure if your JSON is valid, don't use the Unsafe API.

Also, the Unsafe API does not copy the buffer when using Unmarshal API, which, in case of string decoding, can lead to data corruption if a byte buffer is reused. Using the Decode API makes Unsafe API safer as the io.Reader relies on copy builtin method and Decoder will have its own internal buffer :)

Access the Unsafe API this way:

gojay.Unsafe.Unmarshal(b, v)

Documentation

Overview

Package gojay implements encoding and decoding of JSON as defined in RFC 7159. The mapping between JSON and Go values is described in the documentation for the Marshal and Unmarshal functions.

It aims at performance and usability by relying on simple interfaces to decode and encode structures, slices, arrays and even channels.

On top of the simple interfaces to implement, gojay provides lots of helpers to decode and encode multiple of different types natively such as bit.Int, sql.NullString or time.Time

Example (DecodeEncode)
package main

import (
	"fmt"
	"log"
	"os"
	"strings"

	"github.com/francoispqt/gojay"
)

type User struct {
	ID    int
	Name  string
	Email string
}

func (u *User) UnmarshalJSONObject(dec *gojay.Decoder, k string) error {
	switch k {
	case "id":
		return dec.Int(&u.ID)
	case "name":
		return dec.String(&u.Name)
	case "email":
		return dec.String(&u.Email)
	}
	return nil
}

func (u *User) NKeys() int {
	return 3
}

func (u *User) MarshalJSONObject(enc *gojay.Encoder) {
	enc.IntKey("id", u.ID)
	enc.StringKey("name", u.Name)
	enc.StringKey("email", u.Email)
}

func (u *User) IsNil() bool {
	return u == nil
}

func main() {
	reader := strings.NewReader(`{
		"id": 1,
		"name": "John Doe",
		"email": "john.doe@email.com"
	}`)
	dec := gojay.BorrowDecoder(reader)
	defer dec.Release()

	u := &User{}
	err := dec.Decode(u)
	if err != nil {
		log.Fatal(err)
	}

	enc := gojay.BorrowEncoder(os.Stdout)
	err = enc.Encode(u)
	if err != nil {
		log.Fatal(err)
	}

	fmt.Printf("\nUser ID: %d\nName: %s\nEmail: %s\n",
		u.ID, u.Name, u.Email)

}
Output:

{"id":1,"name":"John Doe","email":"john.doe@email.com"}
User ID: 1
Name: John Doe
Email: john.doe@email.com

Variables

View Source
var ErrUnmarshalPtrExpected = errors.New("Cannot unmarshal to given value, a pointer is expected")

ErrUnmarshalPtrExpected is the error returned when unmarshal expects a pointer value, When using `dec.ObjectNull` or `dec.ArrayNull` for example.

View Source
var Stream = stream{}

Stream is a struct holding the Stream api

View Source
var Unsafe = decUnsafe{}

Unsafe is the structure holding the unsafe version of the API. The difference between unsafe api and regular api is that the regular API copies the buffer passed to Unmarshal functions to a new internal buffer. Making it safer because internally GoJay uses unsafe.Pointer to transform slice of bytes into a string.

Functions

func Marshal

func Marshal(v interface{}) ([]byte, error)

Marshal returns the JSON encoding of v.

If v is nil, not an implementation MarshalerJSONObject or MarshalerJSONArray or not one of the following types:

string, int, int8, int16, int32, int64, uint8, uint16, uint32, uint64, float64, float32, bool

Marshal returns an InvalidMarshalError.

Example (Bool)
package main

import (
	"fmt"
	"log"

	"github.com/francoispqt/gojay"
)

func main() {
	b := true
	d, err := gojay.Marshal(b)
	if err != nil {
		log.Fatal(err)
	}
	fmt.Println(string(d)) // true
}
Output:

Example (String)
package main

import (

func MarshalAny

func MarshalAny(v interface{}) ([]byte, error)

MarshalAny returns the JSON encoding of v.

If v is nil, not an implementation MarshalerJSONObject or MarshalerJSONArray or not one of the following types:

string, int, int8, int16, int32, int64, uint8, uint16, uint32, uint64, float64, float32, bool

MarshalAny falls back to "json/encoding" package to marshal the value.

func MarshalJSONArray

func MarshalJSONArray(v MarshalerJSONArray) ([]byte, error)

MarshalJSONArray returns the JSON encoding of v, an implementation of MarshalerJSONArray.

Example:

type TestSlice []*TestStruct

func (t TestSlice) MarshalJSONArray(enc *Encoder) {
	for _, e := range t {
		enc.AddObject(e)
	}
}

func main() {
	test := &TestSlice{
		&TestStruct{123456},

}

func MarshalJSONObject

func MarshalJSONObject(v MarshalerJSONObject) ([]byte, error)

MarshalJSONObject returns the JSON encoding of v, an implementation of MarshalerJSONObject.

Example:

	enc.IntKey("id", s.id)
}
func (s *Object) IsNil() bool {
	return s == nil
}

func main() {
	test := &Object{

	}
	b, _ := gojay.Marshal(test)
	fmt.Println(b) // {"id":123456}
}

func Unmarshal

func Unmarshal(data []byte, v interface{}) error

Unmarshal parses the JSON-encoded data and stores the result in the value pointed to by v. If v is nil, not an implementation of UnmarshalerJSONObject or UnmarshalerJSONArray or not one of the following types:

*uint32, **uint32, *uint64, **uint64, *float64, **float64, *float32, **float32, *bool, **bool

Unmarshal returns an InvalidUnmarshalError.

If a JSON value is not appropriate for a given target type, or if a JSON number overflows the target type, Unmarshal skips that field and completes the unmarshaling as best it can. If no more serious errors are encountered, Unmarshal returns an UnmarshalTypeError describing the earliest such error. In any case, it's not guaranteed that all the remaining fields following the problematic one will be unmarshaled into the target object.

Example (Bool)
package main

import (
	"fmt"
	"log"

	"github.com/francoispqt/gojay"
)

func main() {
	data := []byte(`true`)
	var b bool
	err := gojay.Unmarshal(data, &b)
	if err != nil {
		log.Fatal(err)
	}
	fmt.Println(b) // true
}
Output:

Example (InvalidType)
package main

import (
	"fmt"

	"github.com/francoispqt/gojay"
)

func main() {
	data := []byte(`"gojay"`)
	someStruct := struct{}{}
	err := gojay.Unmarshal(data, &someStruct)

	fmt.Println(err) // "Cannot unmarshal JSON to type '*struct{}'"
}
Output:

Example (String)
package main

import (
	"fmt"
	"log"

	"github.com/francoispqt/gojay"
)

func main() {
	data := []byte(`"gojay"`)
	var str string
	err := gojay.Unmarshal(data, &str)
	if err != nil {
		log.Fatal(err)
	}
	fmt.Println(str) // true
}
Output:

func UnmarshalJSONArray

func UnmarshalJSONArray(data []byte, v UnmarshalerJSONArray) error

UnmarshalJSONArray parses the JSON-encoded data and stores the result in the value pointed to by v.

v must implement UnmarshalerJSONArray.

If a JSON value is not appropriate for a given target type, or if a JSON number overflows the target type, UnmarshalJSONArray skips that field and completes the unmarshaling as best it can.

func UnmarshalJSONObject

func UnmarshalJSONObject(data []byte, v UnmarshalerJSONObject) error

UnmarshalJSONObject parses the JSON-encoded data and stores the result in the value pointed to by v.

v must implement UnmarshalerJSONObject.

If a JSON value is not appropriate for a given target type, or if a JSON number overflows the target type, UnmarshalJSONObject skips that field and completes the unmarshaling as best it can.
