Overall result: ❌✅ regressions and improvements - please read the text below
Our benchmarks found a performance regression caused by this PR.
This might be an actual regression, but it can also be just noise.
Next Steps:
- If the regression was expected or you think it can be justified,
please write a comment with sufficient written justification, and add@rustbot label: +perf-regression-triagedto it, to mark the regression as triaged. - If you think that you know of a way to resolve the regression, try to create
a new PR with a fix for the regression. - If you do not understand the regression or you think that it is just noise,
you can ask the@rust-lang/wg-compiler-performanceworking group for help (members of this group
were already notified of this PR).
