Make fewer types generic over QueryContext While trying to refactor `rustc_query_system::query::QueryContext` to make it dyn-safe, I noticed some smaller things: * QueryConfig doesn't need to be generic over QueryContext * ~~The `kind` field on QueryJobId is unused~~ * Some unnecessary where clauses * Many types in `job.rs` where generic over `QueryContext` but only needed `QueryContext::Query`. If handle_cycle_error() could be refactored to not take `error: CycleError<CTX::Query>`, all those bounds could be removed as well. Changing `find_cycle_in_stack()` in job.rs to not take a `tcx` argument is the only functional change here. Everything else is just updating type signatures. (aka compile-error driven development ^^) ~~Currently there is a weird bug where memory usage suddenly skyrockets when running UI tests. I'll investigate that tomorrow. A perf run probably won't make sense before that is fixed.~~ EDIT: `kind` actually is used by `Eq`, and re-adding it fixed the memory issue. |
