* Introduce QuantifiedWhereClause and DynTy analogous to ChalkFlorian Diebold2021-03-216-98/+197
| | | | | This introduces a bunch of new binders in lots of places, which we have to be careful about, but we had to add them at some point.

|\ | | | | | | | | | | | | | | | | | | 8133: Ignore type bindings in generic_predicates_for_param (fix panic on ena and crates depending on it) r=flodiebold a=flodiebold This allows us to handle more cases without a query cycle, which includes certain cases that rustc accepted. That in turn means we avoid triggering salsa-rs/salsa#257 on valid code (it will still happen if the user writes an actual cycle). We actually accept more definitions than rustc now; that's because rustc only ignores bindings when looking up super traits, whereas we now also ignore them when looking for predicates to disambiguate associated type shorthand. We could introduce a separate query for super traits if necessary, but for now I think this should be fine. Co-authored-by: Florian Diebold <[email protected]>

|\ \ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 7900: show function params in completion detail r=matklad a=JoshMcguigan This resolves #7842 by updating the detail for function completions from `-> T` to `fn(T, U) -> V`. I added an expicit unit test for this, `ide_completion::render::fn_detail_includes_args_and_return_type`, which passes. Lots of other unit tests fail (~60 of them) due to this change, although I believe the failures are purely cosmetic (they were testing the exact format of this output). I'm happy to go update those tests, but before I do that I'd like to make sure this is in fact the format we want for the detail? edit - I realized `UPDATE_EXPECT=1 cargo test` automatically updates `expect!` tests. Big :+1: to whoever worked on that! So I'll go ahead and update all these tests soon. But I still would like to confirm `fn(T, U) -> V` is the desired content in the `detail` field. 8000: Use hir formatter for hover text r=matklad a=oxalica Fix #2765 , (should) fix #4665 Co-authored-by: Josh Mcguigan <[email protected]> Co-authored-by: oxalica <[email protected]>
