Types

type Allocator

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

Allocator for incoming frames, optimized to prevent overwriting after zeroing

func NewAllocator

func NewAllocator() *Allocator

NewAllocator initiates a []byte allocator for frames less than 65536 bytes, the waste(memory fragmentation) of space allocation is guaranteed to be no more than 50%.

func (*Allocator) Get

func (alloc *Allocator) Get(size int) []byte

Get a []byte from pool with most appropriate cap

func (*Allocator) Put

func (alloc *Allocator) Put(buf []byte) error

Put returns a []byte to pool for future use, which the cap must be exactly 2^n
