Types

type DecodeHookFunc

type DecodeHookFunc func(reflect.Kind, reflect.Kind, interface{}) (interface{}, error)

type Decoder

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

A Decoder takes a raw interface value and turns it into structured data, keeping track of rich error information along the way in case anything goes wrong. Unlike the basic top-level Decode method, you can more finely control how the Decoder behaves using the DecoderConfig structure. The top-level Decode method is just a convenience that sets up the most basic Decoder.

func NewDecoder

func NewDecoder(config *DecoderConfig) (*Decoder, error)

NewDecoder returns a new decoder for the given configuration. Once a decoder has been returned, the same configuration must not be used again.

func NewPathDecoder

func NewPathDecoder(config *DecoderConfig) (*Decoder, error)

NewPathDecoder returns a new decoder for the given configuration. This is used to decode path specific structures

func (*Decoder) Decode

func (d *Decoder) Decode(raw interface{}) error

Decode decodes the given raw interface to the target pointer specified by the configuration.

func (*Decoder) DecodePath

func (d *Decoder) DecodePath(m map[string]interface{}, rawVal interface{}) (bool, error)

DecodePath decodes the raw interface against the map based on the specified tags

type DecoderConfig

type DecoderConfig struct {
	// DecodeHook, if set, will be called before any decoding and any
	// type conversion (if WeaklyTypedInput is on). This lets you modify
	// the values before they're set down onto the resulting struct.
	//
	// If an error is returned, the entire decode will fail with that
	// error.
	DecodeHook DecodeHookFunc

	// If ErrorUnused is true, then it is an error for there to exist
	// keys in the original map that were unused in the decoding process
	// (extra keys).
	ErrorUnused bool

	// If WeaklyTypedInput is true, the decoder will make the following
	// "weak" conversions:
	//
	//   - bools to string (true = "1", false = "0")
	//   - numbers to string (base 10)
	//   - bools to int/uint (true = 1, false = 0)
	//   - strings to int/uint (base implied by prefix)
	//   - int to bool (true if value != 0)
	//   - string to bool (accepts: 1, t, T, TRUE, true, True, 0, f, F,
	//     FALSE, false, False. Anything else is an error)
	//   - empty array = empty map and vice versa
	//
	WeaklyTypedInput bool

	// Metadata is the struct that will contain extra metadata about
	// the decoding. If this is nil, then no metadata will be tracked.
	Metadata *Metadata

	// Result is a pointer to the struct that will contain the decoded
	// value.
	Result interface{}

	// The tag name that mapstructure reads for field names. This
	// defaults to "mapstructure"
	TagName string
}

DecoderConfig is the configuration that is used to create a new decoder and allows customization of various aspects of decoding.

type Error

type Error struct {
	Errors []string
}

func (*Error) Error

func (e *Error) Error() string

type Metadata

type Metadata struct {
	// Keys are the keys of the structure which were successfully decoded
	Keys []string

	// Unused is a slice of keys that were found in the raw value but
	// weren't decoded since there was no matching field in the result interface
	Unused []string
}

Metadata contains information about decoding a structure that is tedious or difficult to get otherwise.
