* Add more tests, refactor array lengths/consteval workJade2021-05-141-0/+97
| | | | | | | | | | | Fix #2922: add unknown length as a condition for a type having unknown. Incorporate reviews: * Extract some of the const evaluation workings into functions * Add fixmes on the hacks * Add tests for impls on specific array lengths (these work!!! 😁) * Add tests for const generics (indeed we don't support it yet)
* Add basic support for array lengths in typesJade2021-05-111-1/+1
| | | | | | | | | | This recognizes `let a = [1u8, 2, 3]` as having type `[u8; 3]` instead of the previous `[u8; _]`. Byte strings and `[0u8; 2]` kinds of range array declarations are unsupported as before. I don't know why a bunch of our rustc tests had single quotes inside strings un-escaped by `UPDATE_EXPECT=1 cargo t`, but I don't think it's bad? Maybe something in a nightly?

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 7907: Autoderef with visibility r=cynecx a=cynecx Fixes https://github.com/rust-analyzer/rust-analyzer/issues/7841. I am not sure about the general approach here. Right now this simply tries to check whether the autoderef candidate is reachable from the current module. ~~However this doesn't exactly work with traits (see the `tests::macros::infer_derive_clone_in_core` test, which fails right now).~~ see comment below Refs: - `rustc_typeck` checking fields: https://github.com/rust-lang/rust/blob/66ec64ccf31883cd2c28d045912a76179c0c6ed2/compiler/rustc_typeck/src/check/expr.rs#L1610 r? @flodiebold Co-authored-by: cynecx <[email protected]>

* | Ignore type bindings in generic_predicates_for_paramFlorian Diebold2021-03-211-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.
