rio is a pure Rust library providing safe, misuse-resistant bindings for Linux's io_uring asynchronous I/O interface, built directly on libc without C code generation. It supports both threaded and async usage, with automatic submission handling and backpressure to prevent completion queue overflow.

Use cases

• perform async disk I/O on Linux with io_uring
• build a high-performance storage engine write path
• batch syscalls for high-throughput networking
• use io_uring from Rust without unsafe C bindings
• avoid dropped completions from queue overflow
• integrate io_uring completions with an async runtime or threads

When to choose

• you need io_uring access in Rust with ergonomic, misuse-resistant APIs
• you want both thread-based and async (Future-based) completion handling
• you are building high-performance storage or networking software on Linux

When to avoid

• you need a license other than GPL-3.0 without sponsoring
• you require strict Rust soundness guarantees, since use-after-free is still possible via mem::forget
• you target platforms other than Linux
• you need actively developed features, as the latest release dates to 2022
