It is possible to use an existing buffer with by replacing `New` with `NewBuffer`.


# Blocking vs Non-blocking

The default behavior of the ring buffer is non-blocking, 
meaning that reads and writes will return immediately with an error if the operation cannot be completed.

// New returns a new RingBuffer whose buffer has the given size.
func New(size int) *RingBuffer {
	return &RingBuffer{
		buf:  make([]byte, size),
		size: size,
	}
}

// NewBuffer returns a new RingBuffer whose buffer is provided.
func NewBuffer(b []byte) *RingBuffer {
	return &RingBuffer{
		buf:  b,
		size: len(b),
	}
}

// SetBlocking sets the blocking mode of the ring buffer.
