Make sure async constructs do not `impl Generator` Async lowering turns async functions and blocks into generators internally. Though these special kinds of generators should not `impl Generator` themselves. The other way around, normal generators should not `impl Future`. This was discovered in https://github.com/rust-lang/rust/pull/105082#issuecomment-1332210907 and is a regression from https://github.com/rust-lang/rust/pull/104321. r? `@compiler-errors` |
