Types

type FastBuffer

type FastBuffer struct {
	sync.Mutex
	// contains filtered or unexported fields
}

FastBuffer holds the [][]byte with sync.Mutex to reduce memory allocation.

func NewFastBuffer

func NewFastBuffer() *FastBuffer

NewFastBuffer returns a new FastBuffer.

func (*FastBuffer) Allocate

func (fb *FastBuffer) Allocate(size int) []byte

Allocate allocates the size of []byte from FastBuffer.

func (*FastBuffer) BatchRelease

func (fb *FastBuffer) BatchRelease(d [][]byte)

BatchRelease releases the [][]byte to FastBuffer.

func (*FastBuffer) Release

func (fb *FastBuffer) Release(d []byte)

Release releases the []byte to FastBuffer.

func (*FastBuffer) Reset

func (fb *FastBuffer) Reset()

Reset resets the underlying buffer.
