Build Status Windows Build Status Documentation Crate

Features

  • file-backed memory maps
  • anonymous memory maps
  • synchronous and asynchronous flushing
  • copy-on-write memory maps
  • read-only memory maps
  • stack support (MAP_STACK on unix)
  • executable memory maps
  • huge page support

Platforms

memmap should work on any platform supported by libc. memmap requires Rust stable 1.13 or greater.

memmap is continuously tested on:

  • x86_64-unknown-linux-gnu (Linux)
  • i686-unknown-linux-gnu
  • x86_64-unknown-linux-musl (Linux MUSL)
  • x86_64-apple-darwin (OSX)
  • i686-apple-darwin
  • x86_64-pc-windows-msvc (Windows)
  • i686-pc-windows-msvc
  • x86_64-pc-windows-gnu
  • i686-pc-windows-gnu

memmap is continuously cross-compiled against:

  • arm-linux-androideabi (Android)
  • aarch64-unknown-linux-gnu (ARM)
  • arm-unknown-linux-gnueabihf
  • mips-unknown-linux-gnu (MIPS)
  • x86_64-apple-ios (iOS)
  • i686-apple-ios
