Rust Compiler Performance Triage

A great week, with 170 primary benchmark scenarios seeing improvement. Every PR flagged by perf provided at least some wins, and perhaps more impressive: No rollup PR's were flagged by perf this week! Furthermore, cjgillot fixed an issue where incremental compilation was being unnecessarily hindered by our span and lint system. Great work everyone!

Triage done by @pnkfelix. Revision range: d9297d22..02cd79af

Call for Testing

An important step for RFC implementation is for people to experiment with the implementation and give feedback, especially before stabilization. The following RFCs would benefit from user testing before moving forward:

No RFCs issued a call for testing this week.

If you are a feature implementer and would like your RFC to appear on the above list, add the new call-for-testing label to your RFC along with a comment providing testing instructions and/or guidance on which aspect(s) of the feature need testing.

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.

Final Comment Period

Every week, the team announces the 'final comment period' for RFCs and key PRs which are reaching a decision. Express your opinions now.

Clamps can be pneumatic, Manual and Electric. Clamps are used in linear technology to stop the application in certain position sometime purposely or sometime due to power failure. Zimmer produces clamps for profile rails in linear technology. The frictional connection between the clamping element and the linear guide is generated on the free surfaces of the guide rails, avoiding damage to the running 1 surfaces of the ball guides and roller slides.

✅Compact #design ✅#Lubrication not necessary

✅Rust Protection

✅Used as a safety element
