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.
This Week in Rust is openly developed on GitHub. If you find any errors in this week's issue, please submit a PR.

Rust Compiler Performance Triage
- 2020-11-10: 1 Regression, 2 Improvements, 2 mixed
A mixed week with improvements still outweighing regressions. Perhaps the biggest highlight was the move to compiling rustc crates with the initial-exec TLS model which results in fewer calls to
_tls_get_addr and thus faster compile times.
See the full report for more.
Changes to Rust follow the Rust RFC (request for comments) process. These are the RFCs that were approved for implementation this week:
