The “Conditional compilation” section of the Reference has a list of configurations that must be defined (as of Rust 1.14):

  • target_arch with values like:
    • x86
    • x86_64
    • mips
    • powerpc
    • powerpc64
    • arm
    • aarch64
  • target_os with values like:
    • windows
    • macos
    • ios
    • linux
    • android
    • freebsd
    • dragonfly
    • bitrig
    • openbsd
    • netbsd
  • target_family with values like:
    • unix
    • windows
  • unix (shortcut for target_family)
  • windows (shortcut for target_family)
  • target_env with values like:
    • gnu
    • msvc
    • musl
    • "" (empty string)
  • target_endian with values:
    • little
    • big
  • target_pointer_width with values like:
    • 32
