Rustix is a Rust library providing safe, memory-safe and I/O-safe bindings to POSIX/Unix/Linux/Winsock syscall-like APIs. It offers configurable backends (linux_raw using raw syscalls, or libc) and is a Bytecode Alliance project.

Use cases

• make Linux syscalls from Rust without unsafe code
• avoid libc dependency with raw Linux syscall bindings
• safe file descriptor and I/O handling in Rust
• portable POSIX API bindings across Unix platforms
• Winsock networking bindings for Rust
• low-level syscall wrappers with I/O safety guarantees

When to choose

• you need memory-safe and I/O-safe low-level syscall access in Rust
• you want to avoid libc overhead via the linux_raw backend
• you're building higher-level libraries (like cap-std) on safe syscall primitives
• you need efficient, inlinable syscall wrappers with pointer provenance guarantees

When to avoid

• you need high-level portable APIs rather than low-level syscall bindings
• you need full Windows support beyond Winsock networking
• you prefer using the standard library's std abstractions
• you're not working in Rust
