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
This library does not expose the kernel-space API of the Mach 3.0 kernel
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.
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 = "0.4"
Available crate feature:
- unstable (disabled by default): Exposes newly changed APIs. Enabling this may bring breaking changes (see the breaking change policy).
Breaking change policy
We do the following steps when an item is changed/removed on latest toolchain:
- Deprecate an existing one
- Declare a new one under the
- After a month or more since releasing a new version that contains that change, remove/change an older one
For instance, if const
FOO value is changed from
we expose the newer one, i.e.
unstable users should notice the change on the first release since deprecating.
After a month or more, all the users should notice it.
