If anyone is looking for a project, this should be interesting and would be really useful for the Rust community. Last year I hacked up a system to track performance of the Rust compiler. You can see it here.
The ‘backend of the front end’ is a mess of node.js - https://github.com/nrc/rustc-perf/blob/master/backend/perf.js We’d like to extend what we can do, but before we do that, it would be nice to rewrite in Rust. Improving the frontend would be great too, but not as urgent or a Rust project. Is anyone keen?
