Documentation

Overview

Package encoding is a wrapper for the core functionality of packages like "encoding/json" and "encoding/gob".

It contains the Codec interface and multiple implementations for encoding Go values to other formats and decode from other formats to Go values. Formats can be JSON, gob etc.

Types

type Codec

type Codec interface {
	// Marshal encodes a Go value to a slice of bytes.
	Marshal(v interface{}) ([]byte, error)
	// Unmarshal decodes a slice of bytes into a Go value.
	Unmarshal(data []byte, v interface{}) error
}

Codec encodes/decodes Go values to/from slices of bytes.

type GobCodec

type GobCodec struct{}

GobCodec encodes/decodes Go values to/from gob. You can use encoding.Gob instead of creating an instance of this struct.

func (GobCodec) Marshal

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

Marshal encodes a Go value to gob.

func (GobCodec) Unmarshal

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

Unmarshal decodes a gob value into a Go value.

type JSONcodec

type JSONcodec struct{}

JSONcodec encodes/decodes Go values to/from JSON. You can use encoding.JSON instead of creating an instance of this struct.

func (JSONcodec) Marshal

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

Marshal encodes a Go value to JSON.

func (JSONcodec) Unmarshal

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

Unmarshal decodes a JSON value into a Go value.
