Make libnix visible to com.android.uwb am: a548d0c3ba am: 4f7f1c1f28 am: 92396a5199 Original change: https://android-review.googlesource.com/c/platform/external/rust/crates/nix/+/2615189 Change-Id: I44dab5dd1ec8fcee2db699d87613e66da9e297ca Signed-off-by: Automerger Merge Worker <android-build-automerger-merge-worker@system.gserviceaccount.com>
Nix seeks to provide friendly bindings to various *nix platform APIs (Linux, Darwin, ...). The goal is to not provide a 100% unified interface, but to unify what can be while still providing platform specific APIs.
For many system APIs, Nix provides a safe alternative to the unsafe APIs exposed by the libc crate. This is done by wrapping the libc functionality with types/abstractions that enforce legal/safe usage.
As an example of what Nix provides, examine the differences between what is exposed by libc and nix for the gethostname system call:
// libc api (unsafe, requires handling return code/errno) pub unsafe extern fn gethostname(name: *mut c_char, len: size_t) -> c_int; // nix api (returns a nix::Result<OsString>) pub fn gethostname() -> Result<OsString>;
nix target support consists of two tiers. While nix attempts to support all platforms supported by libc, only some platforms are actively supported due to either technical or manpower limitations. Support for platforms is split into three tiers:
The following targets are supported by nix
:
Tier 1:
Tier 2:
Tier 3:
nix is supported on Rust 1.56.1 and higher. Its MSRV will not be changed in the future without bumping the major or minor version.
