Method WriteByte

fflib/v1/buffer.go:265–269

WriteByte appends the byte c to the buffer, growing the buffer as needed. The returned error is always nil, but is included to match bufio.Writer's WriteByte. If the buffer becomes too large, WriteByte will panic with ErrTooLarge.

(c byte)

// WriteByte. If the buffer becomes too large, WriteByte will panic with
// ErrTooLarge.
func (b *Buffer) WriteByte(c byte) error {
	m := b.grow(1)
	b.buf[m] = c
	return nil
}

func (b *Buffer) Rewind(n int) error {
	b.buf = b.buf[:len(b.buf)-n]
