Finished benchmarking commit (e094dfc16d00959a6087ab70f8eeee5919a1ea0b): comparison url. Summary: This change led to very large relevant mixed results 🤷 in compiler performance.
If you disagree with this performance assessment, please file an issue in rust-lang/rustc-perf. Benchmarking this pull request likely means that it is perf-sensitive, so we're automatically marking it as not fit for rolling up. While you can manually mark this PR as fit for rollup, we strongly recommend not doing so since this PR led to changes in compiler perf. Next Steps: If you can justify the regressions found in this try perf run, please indicate this with @bors rollup=never |

Per #92068 (comment), marking regression as triaged. |
The whole standard library is now on Rust 2021, so the test crates need to use it too. The switch was made in rust-lang/rust#92068.
…ark-Simulacrum Build libcore as 2021 in a few more places The `Cargo.toml` has `edition = "2021"` (as of rust-lang#92068), so that's what these command lines should use too.

Such programming errors will now results in `0` rather than a panic. - In a future release we're planning to increase the baseline requirements for the Linux kernel to version 3.2, and for glibc to version 2.17.

The alloc library was switched to the 2021 edition in <rust-lang/rust#92068>. However, it did not use any features of the new edition until PR <rust-lang/rust#98103>, which relies on the newer closure capture mechanism. This commit fixes the build on the latest nightlies, which include that PR. Fixes #104
The fix for #88638 (comment) is to simply add const-stability for these functions.
r? @m-ou-se
Closes #88638.
