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

Bytes is a pool of byte slices that can be re-used. Slices in this pool will not be garbage collected when not in use.

func NewBytes(max int) *Bytes

NewBytes returns a Bytes pool with capacity for max byte slices to be pool.

func (p *Bytes) Get(sz int) []byte

Get returns a byte slice size with at least sz capacity. Items returned may not be in the zero state and should be reset by the caller.

func (p *Bytes) Put(c []byte)

Put returns a slice back to the pool. If the pool is full, the byte slice is discarded.
