Erase query result types using TAIT #108881

cjgillot · 2023-03-07T21:45:18Z

Got the idea while reviewing #108638.
This PR replace query results with a byte slice when monomorphizing, but uses a TAIT to keep some type safety.

Filed for bootstap timing.

Finished benchmarking commit (de6d288e66f30a1cf067e253fe7474fd92a1c569): comparison URL.

Overall result: ❌ regressions - ACTION NEEDED

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 may lead to changes in compiler perf.

Next Steps: If you can justify the regressions found in this try perf run, please indicate this with @rustbot label: +perf-regression-triaged along with sufficient written justification. If you cannot justify the regressions please fix the regressions and do another perf run. If the next run shows neutral or positive results, the label will be automatically removed.
