Types

type Scanner

type Scanner struct {
	Pos int64 // position in reader
	End int64
	// contains filtered or unexported fields
}

func New

func New(r io.Reader) *Scanner

func (*Scanner) Back

func (s *Scanner) Back()

back undoes a previous call to next(), moving backward one byte in the internal buffer. as we only guarantee a lookback buffer size of one, any subsequent calls to back() before calling next() may panic

func (*Scanner) Cur

func (s *Scanner) Cur() byte

read byte at current position (without advancing)

func (*Scanner) Next

func (s *Scanner) Next() byte

read next byte

func (*Scanner) Remaining

func (s *Scanner) Remaining() int64

remaining returns the number of unread bytes if EOF for the underlying reader has not yet been found, maximum possible integer value will be returned
