How we ship the Rust toolchain

Jakub Beránek

Did you ever wonder what has to happen for a new version of the Rust compiler gets to Rustaceans? I’ll show you!

We will follow the journey of a single Rust commit, from its pull request, through the compiler build system, continuous integration workflows, our myriad of tests, the PGO and BOLT optimization pipeline, to packaging an archive and making a release that can then finally be downloaded by Rust users through rustup. I will also describe various pieces of tooling and bots that help us automate this process to make it as smooth as possible.

Jakub is a member of the Rust Compiler and Infrastructure teams, and currently sits on the Rust Leadership Council.

He contributes to many upstream Rust projects, usually in order to improve the development experience of other Rust maintainers.

Apart from that, he teaches Rust at a university in Ostrava and supports the Rust community in the Czech Republic by organizing and speaking at meetups.
