A Rust library providing a safe, low-level interface to the Linux io_uring asynchronous I/O kernel API. It exposes submission and completion queues with opcodes for file and network operations.

Use cases

• perform asynchronous file I/O in Rust on Linux
• build a high-performance async runtime on io_uring
• do async network I/O with io_uring
• reduce syscall overhead for I/O-heavy workloads
• write low-level io_uring opcodes from Rust

When to choose

• you need direct, low-level control over Linux io_uring from Rust
• you are building an async runtime or I/O library on io_uring
• your project targets Linux kernel 5.6+ and needs maximum I/O performance

When to avoid

• you need cross-platform async I/O (Linux-only API)
• you want a high-level async runtime rather than raw io_uring bindings
• your target kernel is older than 5.1 (or 5.6 for full opcode support)
