Types

type Decoder

type Decoder interface {
	Decode(b []byte, v interface{}) error
}

Decoder decodes the contents of b into a v representation. It's primarily used for decoding contents of a file into a map[string]interface{}.

type DecoderRegistry

type DecoderRegistry struct {
	// contains filtered or unexported fields
}

DecoderRegistry can choose an appropriate Decoder based on the provided format.

func NewDecoderRegistry

func NewDecoderRegistry() *DecoderRegistry

NewDecoderRegistry returns a new, initialized DecoderRegistry.

func (*DecoderRegistry) Decode

func (e *DecoderRegistry) Decode(format string, b []byte, v interface{}) error

Decode calls the underlying Decoder based on the format.

func (*DecoderRegistry) RegisterDecoder

func (e *DecoderRegistry) RegisterDecoder(format string, enc Decoder) error

RegisterDecoder registers a Decoder for a format. Registering a Decoder for an already existing format is not supported.

type Encoder

type Encoder interface {
	Encode(v interface{}) ([]byte, error)
}

Encoder encodes the contents of v into a byte representation. It's primarily used for encoding a map[string]interface{} into a file format.

type EncoderRegistry

type EncoderRegistry struct {
	// contains filtered or unexported fields
}

EncoderRegistry can choose an appropriate Encoder based on the provided format.

func NewEncoderRegistry

func NewEncoderRegistry() *EncoderRegistry

NewEncoderRegistry returns a new, initialized EncoderRegistry.

func (*EncoderRegistry) Encode

func (e *EncoderRegistry) Encode(format string, v interface{}) ([]byte, error)

func (*EncoderRegistry) RegisterEncoder

func (e *EncoderRegistry) RegisterEncoder(format string, enc Encoder) error

RegisterEncoder registers an Encoder for a format. Registering a Encoder for an already existing format is not supported.
