Documentation

Overview

Package allocator implements byte slice pooling management to reduce the pressure of memory allocation.

Functions

func Free

func Free(bts interface{})

Free releases the bytes to pool.

func Malloc

func Malloc(size int) ([]byte, interface{})

Malloc gets a []byte from pool. The second return param is used to Free.

Types

type ClassAllocator

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

ClassAllocator is a bytes pool. The size of bytes satisfies 1 << n.

func NewClassAllocator

func NewClassAllocator() *ClassAllocator

NewClassAllocator creates a new ClassAllocator.

func (*ClassAllocator) Free

func (a *ClassAllocator) Free(bts interface{})

Free releases the bytes to pool.

func (*ClassAllocator) Malloc

func (a *ClassAllocator) Malloc(size int) ([]byte, interface{})

Malloc gets a []byte from pool. The second return param is used to Free. We may also use first return param to Free bytes, but this causes an additional heap allocation. See https://github.com/golang/go/issues/8618 for more details.
