Types

type Pool

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

func NewPool

func NewPool(bitLen int) *Pool

NewPool Creates a pool that will reuse []byte whose length is smaller than (1<<bitLen)-1 .

func (*Pool) Get

func (p *Pool) Get(size int) *[]byte

Get returns a *[]byte from pool with most appropriate cap. It returns a *[]byte with cap of (2^n)-1. If size > pool's maxSize, Get simply calls make([]byte, size).

func (*Pool) Release

func (p *Pool) Release(b *[]byte)

Release releases b to the pool. If cap(b) > pool's maxSize, Release is noop. b should come from Get(). Release will panic if cap(b) is not suitable for the pool.
