Types

type BufReader

type BufReader struct {
	Columns [][]byte
	// contains filtered or unexported fields
}

func NewBufReader

func NewBufReader(rd io.Reader) *BufReader

func (*BufReader) Available

func (b *BufReader) Available() int

func (*BufReader) Buffered

func (b *BufReader) Buffered() int

Buffered returns the number of bytes that can be read from the current buffer.

func (*BufReader) Bytes

func (b *BufReader) Bytes() []byte

func (*BufReader) BytesReader

func (b *BufReader) BytesReader(n int) *BytesReader

func (*BufReader) Discard

func (b *BufReader) Discard(n int) (discarded int, err error)

Discard skips the next n bytes, returning the number of bytes discarded.

If Discard skips fewer than n bytes, it also returns an error. If 0 <= n <= b.Buffered(), Discard is guaranteed to succeed without reading from the underlying io.BufReader.

func (*BufReader) Read

func (b *BufReader) Read(p []byte) (n int, err error)

func (*BufReader) ReadByte

func (b *BufReader) ReadByte() (byte, error)

func (*BufReader) ReadBytes

func (b *BufReader) ReadBytes(fn func(byte) bool) (line []byte, err error)

func (*BufReader) ReadFull

func (b *BufReader) ReadFull() ([]byte, error)

func (*BufReader) ReadFullTemp

func (b *BufReader) ReadFullTemp() ([]byte, error)

func (*BufReader) ReadN

func (b *BufReader) ReadN(n int) (line []byte, err error)

func (*BufReader) ReadSlice

func (b *BufReader) ReadSlice(delim byte) (line []byte, err error)

ReadSlice reads until the first occurrence of delim in the input, returning a slice pointing at the bytes in the buffer. The bytes stop being valid at the next read. If ReadSlice encounters an error before finding a delimiter, it returns all the data in the buffer and the error itself (often io.EOF). ReadSlice fails with error ErrBufferFull if the buffer fills without a delim. Because the data returned from ReadSlice will be overwritten by the next I/O operation, most clients should use ReadBytes or ReadString instead. ReadSlice returns err != nil if and only if line does not end in delim.

func (*BufReader) Reset

func (b *BufReader) Reset(rd io.Reader)

func (*BufReader) SetAvailable

func (b *BufReader) SetAvailable(n int)

func (*BufReader) UnreadByte

func (*BytesReader) ReadByte

func (r *BytesReader) ReadByte() (byte, error)

func (*BytesReader) ReadBytes
