Types ¶

type Buffer ¶

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

Buffer is a ReadWriteCloser that supports seeking. It's intended to replicate the functionality of bytes.Buffer that I use in my projects.

Note that the seeking is limited to the read marker; all writes are append-only.

func New ¶

func New(data []byte) *Buffer

func (*Buffer) Bytes ¶

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

Bytes returns the underlying bytes from the current position.

func (*Buffer) Close ¶

func (b *Buffer) Close() error

Close clears all the data out of the buffer and sets the read position to 0.

func (*Buffer) Len ¶

func (b *Buffer) Len() int

Len returns the length of data remaining to be read.

func (*Buffer) Read ¶

func (b *Buffer) Read(p []byte) (int, error)

func (*Buffer) Rewind ¶

func (b *Buffer) Rewind()

Rewind resets the read pointer to 0.

func (*Buffer) Seek ¶

func (b *Buffer) Seek(pos int)

Seek sets the read pointer to pos.

func (*Buffer) Write ¶

func (b *Buffer) Write(p []byte) (int, error)
