type Decoder ¶

type Decoder interface {
	// PeekKind returns the Kind of the next token without consuming it.
	PeekKind() Kind
	// ReadToken reads the next token and returns its string value, kind, and error.
	ReadToken() (token string, _ Kind, _ error)
	// ReadValue reads the next value, which may be a complete JSON
	// node (object, array, or scalar), as bytes.
	ReadValue() (value []byte, _ error)
	// SkipValue skips the next value (maybe a complete JSON node).
	SkipValue() error
}

Decoder defines a streaming JSON decoder interface.

Only the lowest level interface is preserved, higher level requires some shallow encapsulation.

type Encoder ¶

type Encoder interface {
	// WriteValue writes a JSON value to the encoder.
	WriteValue(v []byte) error
}

Encoder defines a streaming JSON encoder interface.

Only the lowest level interface is preserved, higher level requires some shallow encapsulation.

type Kind ¶

type Kind byte

Kind represents each possible JSON token kind with a single byte, which is conveniently the first byte of that kind's grammar with the restriction that numbers always be represented with '0':

• 'n': null
• 'f': false
• 't': true
• '"': string
• '0': number
• '{': object begin
• '}': object end
• '[': array begin
• ']': array end

An invalid kind is usually represented using 0, but may be non-zero due to invalid JSON data.

const InvalidKind Kind = 0
