Functions

func Bool

func Bool(i interface{}) bool

Bool converts <i> to bool. It returns false if <i> is: false, "", 0, "false", "off", "no", empty slice/map.

func Byte

func Byte(i interface{}) byte

Byte converts <i> to byte.

func Bytes

func Bytes(i interface{}) []byte

Bytes converts <i> to []byte.

func Convert

func Convert(i interface{}, t string, params ...interface{}) interface{}

Convert converts the variable <i> to the type <t>, the type <t> is specified by string. The unnecessary parameter <params> is used for additional parameter passing.

func Duration

func Duration(i interface{}) time.Duration

Duration converts <i> to time.Duration. If <i> is string, then it uses time.ParseDuration to convert it. If <i> is numeric, then it converts <i> as nanoseconds.

func Float32

func Float32(i interface{}) float32

Float32 converts <i> to float32.

func Float64

func Float64(i interface{}) float64

Float64 converts <i> to float64.

func Floats

func Floats(i interface{}) []float64

Strings converts <i> to []float64.

func GTime

func GTime(i interface{}, format ...string) *gtime.Time

GTime converts <i> to *gtime.Time. The parameter <format> can be used to specify the format of <i>. If no <format> given, it converts <i> using gtime.NewFromTimeStamp if <i> is numeric, or using gtime.StrToTime if <i> is string.

func Int

func Int(i interface{}) int

Int converts <i> to int.

func Int16

func Int16(i interface{}) int16

Int16 converts <i> to int16.

func Int32

func Int32(i interface{}) int32

Int32 converts <i> to int32.

func Int64

func Int64(i interface{}) int64

Int64 converts <i> to int64.

func Int8

func Int8(i interface{}) int8

Int8 converts <i> to int8.

func Interfaces

func Interfaces(i interface{}) []interface{}

Interfaces converts <i> to []interface{}.

func Ints

func Ints(i interface{}) []int

Ints converts <i> to []int.

func Map

func Map(value interface{}, tags ...string) map[string]interface{}

Map converts any variable <value> to map[string]interface{}.

If the parameter <value> is not a map/struct/*struct type, then the conversion will fail and returns nil.

If <value> is a struct/*struct object, the second parameter <tags> specifies the most priority tags that will be detected, otherwise it detects the tags in order of: gconv, json, and then the field name.

func MapDeep

func MapDeep(value interface{}, tags ...string) map[string]interface{}

MapDeep do Map function recursively. See Map.

func MapStruct

func MapStruct(params interface{}, pointer interface{}, mapping ...map[string]string) error

MapStruct converts map type variable <params> to another map type variable <pointer>. The elements of <pointer> should be type of struct/*struct.

func MapStructDeep

func MapStructDeep(params interface{}, pointer interface{}, mapping ...map[string]string) error

MapStructDeep recursively converts map type variable <params> to another map type variable <pointer>. The elements of <pointer> should be type of struct/*struct.

func MapStructs

func MapStructs(params interface{}, pointer interface{}, mapping ...map[string]string) error

MapStructs converts map type variable <params> to another map type variable <pointer>. The elements of <pointer> should be type of []struct/[]*struct.

func MapStructsDeep

func MapStructsDeep(params interface{}, pointer interface{}, mapping ...map[string]string) error

MapStructsDeep recursively converts map type variable <params> to another map type variable <pointer>. The elements of <pointer> should be type of []struct/[]*struct.

func Maps

func Maps(value interface{}, tags ...string) []map[string]interface{}

Maps converts <i> to []map[string]interface{}.

func MapsDeep

func MapsDeep(value interface{}, tags ...string) []map[string]interface{}

MapsDeep converts <i> to []map[string]interface{} recursively.

func Rune

func Rune(i interface{}) rune

Rune converts <i> to rune.

func Runes

func Runes(i interface{}) []rune

Runes converts <i> to []rune.

func SliceAny

func SliceAny(i interface{}) []interface{}

SliceAny is alias of Interfaces.

func SliceFloat

func SliceFloat(i interface{}) []float64

SliceFloat is alias of Floats.

func SliceInt

func SliceInt(i interface{}) []int

SliceInt is alias of Ints.

func SliceMap

func SliceMap(i interface{}) []map[string]interface{}

SliceMap is alias of Maps.

func SliceMapDeep

func SliceMapDeep(i interface{}) []map[string]interface{}

SliceMapDeep is alias of MapsDeep.

func SliceStr

func SliceStr(i interface{}) []string

SliceStr is alias of Strings.

func SliceStruct

func SliceStruct(params interface{}, pointer interface{}, mapping ...map[string]string) (err error)

SliceStruct is alias of Structs.

func SliceStructDeep

func SliceStructDeep(params interface{}, pointer interface{}, mapping ...map[string]string) (err error)

SliceStructDeep is alias of StructsDeep.

func String

func String(i interface{}) string

String converts <i> to string.

func Strings

func Strings(i interface{}) []string

Strings converts <i> to []string.

func Struct

func Struct(params interface{}, pointer interface{}, mapping ...map[string]string) error

Struct maps the params key-value pairs to the corresponding struct object's properties. The third parameter <mapping> is unnecessary, indicating the mapping rules between the custom key name and the attribute name(case sensitive).

Note:

  1. The <params> can be any type of map/struct, usually a map.
  2. The second parameter <pointer> should be a pointer to the struct object.
  3. Only the public attributes of struct object can be mapped.
  4. If <params> is a map, the key of the map <params> can be lowercase. It will automatically convert the first letter of the key to uppercase in mapping procedure to do the matching. It ignores the map key, if it does not match.

func StructDeep

func StructDeep(params interface{}, pointer interface{}, mapping ...map[string]string) error

StructDeep do Struct function recursively. See Struct.

func Structs

func Structs(params interface{}, pointer interface{}, mapping ...map[string]string) (err error)

Structs converts any slice to given struct slice.

func StructsDeep

func StructsDeep(params interface{}, pointer interface{}, mapping ...map[string]string) (err error)

StructsDeep converts any slice to given struct slice recursively.

func Time

func Time(i interface{}, format ...string) time.Time

Time converts <i> to time.Time.

func Uint

func Uint(i interface{}) uint

Uint16 converts <i> to uint16.

func Uint32

func Uint32(i interface{}) uint32

Uint32 converts <i> to uint32.

func Uint64

func Uint64(i interface{}) uint64

Uint64 converts <i> to uint64.

func Uint8

UnsafeBytesToStr converts []byte to string without memory copy.

func UnsafeStrToBytes

func UnsafeStrToBytes(s string) []byte

UnsafeStrToBytes converts string to []byte without memory copy.
