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 three 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:
Platforms not listed are supported on a best-effort basis, relying on our users to report any problems.
The following targets are supported by nix
:
nix is supported on Rust 1.65 and higher. Its MSRV will not be changed in the future without bumping the major or minor version.
