byteswriter

This Go package implements a io.Writer that wraps a []byte. It's like bytes.Reader, but then a Writer.

b := make([]byte, 20)
w := byteswriter.NewWriter(b)
// use io.Writer w

Overview

Contains a io.Writer that is backed by a []byte. It's the bytes.Writer that's missing in the Go standard library.

Index

• type Writer
  • func NewWriter(buf []byte) *Writer
  • func (w *Writer) Seek(offset int64, whence int) (int64, error)
  • func (w *Writer) Write(p []byte) (n int, err error)

Types

type Writer

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

A Writer implements io.Writer and io.Seeker by writing to the given byteslice. Unlike a bytes.Buffer, BytesWriter does not resize the byte slice.

func NewWriter

func NewWriter(buf []byte) *Writer

Create a new writer using the given buffer

func (*Writer) Seek

func (w *Writer) Seek(offset int64, whence int) (int64, error)

func (*Writer) Write

func (w *Writer) Write(p []byte) (n int, err error)
