lio

lio is a low-level I/O project centered on explicit control.

The main crate exposes syscall-shaped, non-blocking operations without imposing an executor or runtime model. Instead of hiding submission and completion behind a framework, lio lets the caller decide how work is driven, how completions are consumed, and which backend is used underneath.

This repository contains:

• lio: the main cross-platform I/O crate
• lio-uring: the Linux io_uring backend crate
• examples/busybox: a larger example application built on top of lio

The project is still evolving, but the direction is stable: stay low-level, preserve explicit ownership and control, and keep the abstraction close to the operating system.
