Functions

func Free

func Free(b []byte)

Free frees the specified slice.

func New

func New(n int) []byte

New allocates a slice of size n. The returned slice is from manually managed memory and MUST be released by calling Free. Failure to do so will result in a memory leak.

Types

type Allocator

type Allocator struct {
	RefCnt *atomic.Int64
}

Allocator is a manual allocator for memory.

func (Allocator) Alloc

func (a Allocator) Alloc(n int) []byte

Alloc allocates a new byte slice with the given size.

func (Allocator) CheckRefCnt

func (a Allocator) CheckRefCnt() error

CheckRefCnt checks whether there is memory leak.

func (Allocator) Free

func (a Allocator) Free(b []byte)

Free frees the byte slice.
