type Parser

type Parser interface {
	// Parse parses a JSON-encoded value and returns the parse result.
	// The value returned remains valid till the next Parse or ParseBytes call.
	Parse(str string) (*value.Value, error)

	// ParseBytes parses a byte slice and returns the parse result.
	// The value returned remains valid till the next Parse or ParseBytes call.
	ParseBytes(b []byte) (*value.Value, error)
}

Parser parses JSON-encoded values.

func NewParser
