## What it is
A Rust crate providing safe, friendly bindings to Unix-like platform APIs (Linux, macOS, BSD, etc.), wrapping unsafe libc calls in typed, Result-based abstractions. It is one of the most widely downloaded Rust libraries for system-level programming.

## Use cases
- call unix system calls from rust safely
- get hostname or process info in rust
- avoid unsafe libc code in rust
- write cross-platform unix tooling in rust
- manage file descriptors, signals, or processes in rust

## When to choose
- you need safe, idiomatic Rust wrappers around POSIX/*nix syscalls
- you want errno handling handled for you via Result types
- you target Linux, macOS, or BSD from Rust

## When to avoid
- you need Windows-only APIs
- you want a fully unified cross-platform OS abstraction layer
- you need raw unsafe libc access with exact C semantics

## Facets
- artifact type: library
- maturity: active
- function: developer-tools, concurrency, file-system, networking
- domain: developer-tools, operating-systems, cross-platform
- platform: rust, bsd, cross-platform
- tags: libc, unix, system-programming, safe-bindings, syscall, linux, macos
