type LazySlice ¶

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

LazySlice holds 0 or 1 slices from a particular Pool.

func (b *LazySlice) Acquire() []byte

func (b *LazySlice) Release()

type Pool ¶

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

Pool wraps a sync.Pool of *[]byte. To encourage correct usage, all public methods are on slicepool.LazySlice.

All copies of a Pool refer to the same underlying pool.

"*[]byte" is used to avoid a heap allocation when passing a []byte to sync.Pool.Put, which leaks its argument to the heap.

func MakePool(sliceLen int) Pool

func (p *Pool) LazySlice() LazySlice
