Merge "Upgrade rust/crates/nix to 0.22.1" am: eee0bbf293 am: 7e7a7d9843 Original change: https://android-review.googlesource.com/c/platform/external/rust/crates/nix/+/1832968 Change-Id: I3d259f910bd3fb5b74dc4fb1295fb15a574e7d04
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<CStr>) pub fn gethostname<'a>(buffer: &'a mut [u8]) -> Result<&'a CStr>;
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
requires Rust 1.41.0 or newer.
To use nix
, add this to your Cargo.toml
:
[dependencies] nix = "0.22.1"
