bufpool

Documentation

Overview

Package bufpool implements size-classed, sharded byte-slice pools.

Buffers are bucketed by capacity, so a small Get does not receive a previously-released multi-MiB slice. The pool stores *[]byte to avoid the interface-conversion allocation that putting a []byte directly into sync.Pool incurs.

Functions

func Get

func Get(hint int) *[]byte

Get returns a *[]byte with cap >= hint and length 0. Anything larger than classHuge is allocated outside the pool.

func Put

func Put(b *[]byte)

Put returns b to the pool. Buffers grown past classHuge are dropped so the GC can reclaim them.
