This bug is to discuss the delays and problems we may encounter in an effort to emit Rust coverage on a nightly schedule.
For example, Changes to the Rust coverage collection is not realized by our CI for many weeks after landing: Delay is currently caused by Rust's beta testing cycle, and our own compiler upgrade schedule.
Summary: [meta] Generate Rust coverage on a nightly schedule → [discuss] Blockers for generate Rust coverage on a nightly schedule
Rust 1.20.0 is now the stable version, so the GCOV profiling option is supported. In order to actually use it, we just need to put a custom version of rustc with the profiling option enabled on tooltool (I've done this to generate the build in bug 1335518). Other blockers are now blockers of bug 1335518.
