Method readByte

pkg/buffer/buffer.go:584–592

readByte implements the io.ByteReader interface. This method is used by BufferReader to consume its underlying buffer. To perform io operations on buffers directly, use ReadToWriter or WriteToReader.

// BufferReader to consume its underlying buffer. To perform io operations on
// buffers directly, use ReadToWriter or WriteToReader.
func (b *Buffer) readByte() (byte, error) {
	if b.Size() == 0 {
		return 0, io.EOF
	}
	v := b.data.Front()
	bt := v.AsSlice()[0]
	b.TrimFront(1)
	return bt, nil
}

// AsBufferReader returns the Buffer as a BufferReader capable of io methods.
// The new BufferReader takes ownership of b.
