types

The types package provides some useful types which implement the sql.Scanner and driver.Valuer interfaces, suitable for use as scan and value targets with database/sql.

Types

type GzippedText

type GzippedText []byte

func (*GzippedText) Scan

func (g *GzippedText) Scan(src interface{}) error

func (GzippedText) Value

func (g GzippedText) Value() (driver.Value, error)

type JsonText

type JsonText json.RawMessage

JsonText is a json.RawMessage, which is a []byte underneath. Value() validates the json format in the source, and returns an error if the json is not valid. Scan does no validation. JsonText additionally implements `Unmarshal`, which unmarshals the json within to an interface{}

func (*JsonText) MarshalJSON

func (j *JsonText) MarshalJSON() ([]byte, error)

Returns the *j as the JSON encoding of j.

func (*JsonText) Scan

func (j *JsonText) Scan(src interface{}) error

Scan stores the src in *j. No validation is done.

func (*JsonText) Unmarshal

func (j *JsonText) Unmarshal(v interface{}) error

Unmarshal unmarshal's the json in j to v, as in json.Unmarshal.

func (*JsonText) UnmarshalJSON

func (j *JsonText) UnmarshalJSON(data []byte) error

UnmarshalJSON sets *j to a copy of data

func (JsonText) Value

func (j JsonText) Value() (driver.Value, error)

Value returns j as a value. This does a validating unmarshal into another RawMessage. If j is invalid json, it returns an error.
