A Rust interface to the user-space API of the Mach 3.0 kernel exposed in /usr/include/mach that underlies macOS and is linked via libSystem (and libsystem_kernel).

This library does not expose the kernel-space API of the Mach 3.0 kernel exposed in SDK/System/Library/Frameworks/Kernel.framework/Versions/A/Headers/mach.

That is, if you are writing a kernel-resident device drivers or some other kernel extensions you have to use something else. The user-space kernel API is often API-incompatible with the kernel space one, and even in the cases where they match, they are sometimes ABI incompatible such that using this library would have undefined behavior.

Usage

Add the following to your Cargo.toml to conditionally include mach on those platforms that support it.

[target.'cfg(any(target_os = "macos", target_os = "ios"))'.dependencies.mach]
version = "0.3"

The following crate features are available:

• deprecated (disabled by default): exposes deprecated APIs that have been removed from the latest versions of the MacOS SDKs. The behavior of using these APIs on MacOS versions that do not support them is undefined (hopefully a linker error).

Platform support

The following table describes the current CI set-up:

Target	Min. Rust	XCode	build	ctest	run
x86_64-apple-darwin	1.33.0	6.4 - 10.0	✓	✓	✓
i686-apple-darwin	1.33.0	6.4 - 10.0	✓	✓	✓
i386-apple-ios	1.33.0	6.4 - 9.4 [0]	✓	-	-
x86_64-apple-ios	1.33.0	6.4 - 10.0	✓	-	-

[0] i386-apple-ios is deprecated in XCode 10.0.

Contribution

Unless you explicitly state otherwise, any contribution intentionally submitted for inclusion in mach by you, as defined in the Apache-2.0 license, shall be triple licensed as above, without any additional terms or conditions.

To locally test the library, run:

TARGET=x86_64-apple-darwin TRAVIS_RUST_VERSION=nightly ./ci/run.sh

where you can replace the TARGET and TRAVIS_RUST_VERSION with the target you want to test (e.g. i686-apple-darwin) and the Rust version you want to use for the tests (e.g. stable, 1.33.0, etc.).
