func Pretouch(vt reflect.Type, opts ...option.CompileOption) error
Pretouch compiles vt ahead-of-time to avoid JIT compilation on-the-fly, in order to reduce the first-hit latency.
Opts are the compile options, for example, "option.WithCompileRecursiveDepth" is a compile option to set the depth of recursive compile for the nested struct type.
func Skip(data []byte) (start int, end int)
Skip skips only one json value, and returns first non-blank character position and its ending position if it is valid. Otherwise, returns negative error code using start and invalid character position using end
Decoder is the decoder context object
type Decoder struct {
// contains filtered or unexported fields
}
func NewDecoder(s string) *Decoder
NewDecoder creates a new decoder instance.
func (self *Decoder) CheckTrailings() error
func (self *Decoder) CopyString()
CopyString indicates the Decoder to decode string values by copying instead of referring.
func (self *Decoder) Decode(val interface{}) error
Decode parses the JSON-encoded data from current position and stores the result in the value pointed to by val.
func (self *Decoder) DisallowUnknownFields()
DisallowUnknownFields indicates the Decoder to return an error when the destination is a struct and the input contains object keys which do not match any non-ignored, exported fields in the destination.
func (self *Decoder) Pos() int
Pos returns the current decoding position.
func (self *Decoder) Reset(s string)
func (self *Decoder) SetOptions(opts Options)
func (self *Decoder) UseInt64()
UseInt64 indicates the Decoder to unmarshal an integer into an interface{} as an int64 instead of as a float64.
func (self *Decoder) UseNumber()
UseNumber indicates the Decoder to unmarshal a number into an interface{} as a json.Number instead of as a float64.
func (self *Decoder) UseUnicodeErrors()
UseUnicodeErrors indicates the Decoder to return an error when encounter invalid UTF-8 escape sequences.
func (self *Decoder) ValidateString()
ValidateString causes the Decoder to validate string values when decoding string value in JSON. Validation is that, returning error when unescaped control chars(0x00-0x1f) or invalid UTF-8 chars in the string value of JSON.

StreamDecoder is the decoder context object for streaming input.
type StreamDecoder struct {
Decoder
// contains filtered or unexported fields
}
func NewStreamDecoder(r io.Reader) *StreamDecoder
NewStreamDecoder adapts to encoding/json.NewDecoder API.
NewStreamDecoder returns a new decoder that reads from r.
func (self *StreamDecoder) Buffered() io.Reader
Buffered returns a reader of the data remaining in the Decoder's buffer. The reader is valid until the next call to Decode.
func (self *StreamDecoder) Decode(val interface{}) (err error)
Decode decodes input stream into val with corresponding data. Redundantly bytes may be read and left in its buffer, and can be used at next call. Either io error from underlying io.Reader (except io.EOF) or syntax error from data will be recorded and stop subsequently decoding.
func (self *StreamDecoder) InputOffset() int64
InputOffset returns the input stream byte offset of the current decoder position. The offset gives the location of the end of the most recently returned token and the beginning of the next token.
func (self *StreamDecoder) More() bool
More reports whether there is another element in the current array or object being parsed.
type SyntaxError struct {
Pos int
Src string
Code types.ParsingError
Msg string
}
func (self SyntaxError) Description() string
func (self SyntaxError) Error() string
func (self SyntaxError) Message() string
