Hello and welcome to another issue of This Week in Rust! Rust is a systems language pursuing the trifecta: safety, concurrency, and speed. This is a weekly summary of its progress and community. Want something mentioned? Tweet us at @ThisWeekInRust or send us a pull request. Want to get involved? We love contributions.
- Writing an OS in Rust: Hardware interrupts.
- Towards fearless SIMD.
- Shifgrethor I: Garbage collection as a Rust library.
- Update on the October 15, 2018 incident on crates.io.
- docs.rs is now part of the rust-lang-nursery organization.
- Is Rust functional?
- Multithreading Rust and WebAssembly.
- Rust has higher kinded types already... sort of.
- Auth web microservice with Rust using actix-web.
Always wanted to contribute to open-source projects but didn't know where to start? Every week we highlight some tasks from the Rust community for you to pick and get started!
Some of these tasks may also have mentors available, visit the task page for more information.
If you are a Rust project owner and are looking for contributors, please submit tasks here.
