Compio is a thread-per-core asynchronous Rust runtime built on completion-based I/O, using io_uring on Linux, IOCP on Windows, and polling fallbacks elsewhere. It provides high-level async filesystem and networking APIs as well as low-level proactor driver access, inspired by monoio.

Use cases

• build a high-performance async network server in Rust
• run async file I/O with io_uring on Linux
• write a thread-per-core Rust application without tokio
• use completion-based I/O with IOCP on Windows
• inspect async tasks with tokio-console in a non-tokio runtime
• replace monoio with an actively maintained alternative

When to choose

• you want maximum I/O performance via io_uring or IOCP in Rust
• you prefer thread-per-core architecture over work-stealing runtimes
• you need async filesystem and networking APIs outside the tokio ecosystem

When to avoid

• you need tokio's ecosystem compatibility and broad middleware support
• your target platforms lack io_uring/IOCP and polling fallback performance is insufficient
• you need a work-stealing multi-threaded scheduler
