Documentation

Overview

Package pools provides a collection of pools which provide various data types with buffers. These can be used to lower the number of memory allocations and reuse buffers.

New pools should be added to this package to allow them to be shared across packages.

Utility functions which operate on pools should be added to this package to allow them to be reused.

Types

type BufioReaderPool

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

func (*BufioReaderPool) Get

func (bufPool *BufioReaderPool) Get(r io.Reader) *bufio.Reader

Get returns a bufio.Reader which reads from r. The buffer size is that of the pool.

func (*BufioReaderPool) NewReadCloserWrapper

func (bufPool *BufioReaderPool) NewReadCloserWrapper(buf *bufio.Reader, r io.Reader) io.ReadCloser

NewReadCloserWrapper returns a wrapper which puts the bufio.Reader back into the pool and closes the reader if it's an io.ReadCloser.

func (*BufioReaderPool) Put

func (bufPool *BufioReaderPool) Put(b *bufio.Reader)

Put puts the bufio.Reader back into the pool.

type BufioWriterPool

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

func (*BufioWriterPool) Get

func (bufPool *BufioWriterPool) Get(w io.Writer) *bufio.Writer

Get returns a bufio.Writer which writes to w. The buffer size is that of the pool.

func (*BufioWriterPool) NewWriteCloserWrapper

func (bufPool *BufioWriterPool) NewWriteCloserWrapper(buf *bufio.Writer, w io.Writer) io.WriteCloser

NewWriteCloserWrapper returns a wrapper which puts the bufio.Writer back into the pool and closes the writer if it's an io.Writecloser.

func (*BufioWriterPool) Put

func (bufPool *BufioWriterPool) Put(b *bufio.Writer)
