glommio

ATTENTION If you are confused between this and Scipio, this project was previously called Scipio but had to be very unfortunately renamed due to a trademark dispute. This disclaimer will self-destruct as soon as people have enough time to switch over. We would also like to make sure to clarify that this doesn't change our opinion on Scipio Africanus being such a great and underrated general that deserved a lot better from Rome than what we got.

What is Glommio?

Glommio (pronounced glo-mee-jow or |glomjəʊ|) is a Cooperative Thread-per-Core crate for Rust & Linux based on io_uring. Like other rust asynchronous crates it allows one to write asynchronous code that takes advantage of rust async/await, but unlike its counterparts it doesn't use helper threads anywhere.

Using Glommio is not hard if you are familiar with rust async. All you have to do is:

    use glommio::prelude::*;
    LocalExecutorBuilder::new().spawn(|| async move {
        /// your code here
    }).unwrap();

Status

Glommio is still considered an alpha release. The main reasons are:

The existing API is still evolving
There are still some uses of unsafe that can be avoided
There are features that are critical for a good thread per core system that are not implemented yet. The top two are:
- communication channels between executors so we can pass Send data.
- per-shard memory allocator.
