Rust Compiler Performance Triage
A mixed week: some minor regressions, but things overall improved for instruction counts.
Max RSS has gone up slightly over the past month, on the order of 0.5% regression according to benchmark summary. pnkfelix is following up on that with rustc-perf team on zulip
Triage done by @pnkfelix. Revision range: 3ea44938..3e751467
4 Regressions, 5 Improvements, 4 Mixed; 3 of them in rollups 63 comparisons made in total
Approved RFCs
Changes to Rust follow the Rust RFC (request for comments) process. These are the RFCs that were approved for implementation this week:
- No RFCs were approved this week.

Quote of the Week
All that to say that Rust does precisely this great job at decoupling some of these notions that have been, historically, quite tangled for a while; and for those used to that environment with everything muddied, it can be a bit hard to take a step back and rethink these distinctions that Rust makes.
Thanks to H2CO3 for the suggestion!
