package mmap

import "golang.org/x/exp/mmap"

Package mmap provides a way to memory-map a file.


Package Files


type ReaderAt Uses

type ReaderAt struct {
    // contains filtered or unexported fields

ReaderAt reads a memory-mapped file.

Like any io.ReaderAt, clients can execute parallel ReadAt calls, but it is not safe to call Close and reading methods concurrently.

func Open Uses

func Open(filename string) (*ReaderAt, error)

Open memory-maps the named file for reading.

func (*ReaderAt) At Uses

func (r *ReaderAt) At(i int) byte

At returns the byte at index i.

func (*ReaderAt) Close Uses

func (r *ReaderAt) Close() error

Close closes the reader.

func (*ReaderAt) Len Uses

func (r *ReaderAt) Len() int

Len returns the length of the underlying memory-mapped file.

func (*ReaderAt) ReadAt Uses

func (r *ReaderAt) ReadAt(p []byte, off int64) (int, error)

ReadAt implements the io.ReaderAt interface.
