func (b *Buff) Reset()

func (*Buff) SetSize

func (b *Buff) SetSize(size int)

func (*Buff) Size

func (b *Buff) Size() int

func (*Buff) ToBytes

func (b *Buff) ToBytes() []byte

type Writer

type Writer struct {
	// contains filtered or unexported fields
}

func NewWriter

func NewWriter(w io.Writer) *Writer

NewWriter returns a new Writer whose buffer has the default size.

func NewWriterSize

func NewWriterSize(w io.Writer, size int) *Writer

NewWriterSize returns a new Writer whose buffer has at least the specified size, it returns the underlying Writer.

func (*Writer) Available

func (b *Writer) Available() int

Available returns how many bytes are unused in the buffer.

func (*Writer) Buffered

func (b *Writer) Buffered() int

Buffered returns the number of bytes that have been written into the current buffer.

func (*Writer) Flush

func (b *Writer) Flush() error

Flush writes any buffered data to the underlying io.Writer.

func (*Writer) Free

func (b *Writer) Free()

func (*Writer) Reset

func (b *Writer) Reset(w io.Writer)

Reset discards any unflushed buffered data, clears any error, and resets b to write its output to w.

func (*Writer) Size

func (b *Writer) Size() int

Size returns the size of the underlying buffer in bytes.

func (*Writer) Write

func (b *Writer) Write(p []byte) (nn int, err error)

Write writes the contents of p into the buffer. It returns the number of bytes written. If nn < len(p), it also returns an error explaining why the write is short.
