* Fix type mismatch caused by macrosFlorian Diebold2021-05-251-0/+44
| | | | | | MacroStmts should be completely transparent, but it prevented coercion. (I should maybe give `infer_expr` and `infer_expr_inner` better names.)

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 8813: Get some more array lengths! r=lf- a=lf- This is built on #8799 and thus contains its changes. I'll rebase it onto master when that one gets merged. It adds support for r-a understanding the length of: * `let a: [u8; 2] = ...` * `let a = b"aaa"` * `let a = [0u8; 4]` I have added support for getting the values of byte strings, which was not previously there. I am least confident in the correctness of this part and it probably needs some more tests, as we currently have only one test that exercised that part (!). Fixes #2922.

| * Add more tests, refactor array lengths/consteval workJade2021-05-142-1/+106
| | | | | | | | | | | | | | | | | | | | | | 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)
| * Test lowering byte strings some moreJade2021-05-131-14/+25
| |
| * Add support for lengths in array repeats, if they are literalsJade2021-05-131-1/+1
| | | | | | | | Now we will get the type of `[0u8; 4]`.
| * Support length for ByteStringsJade2021-05-131-2/+2
| | | | | | | | I am not confident that my added byte string parsing is right.
| * Add lowering of array lengths in typesJade2021-05-133-34/+34
| | | | | | | | | | | | | | | | | | | | | | Now e.g. ```rust fn a(b: [u8; 2]) { } ``` will know about the length of b.

* Merge #8799bors[bot]2021-05-125-95/+95
|\ | | | | | | | | | | | | | | | | | | | | | | | | | | 8799: Add basic support for array lengths in types r=flodiebold a=lf- 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?

| | | | | | | This isn't actually how it works, you have to specify the exact trait that has the associated type. Fixes #8686.

* Fix crash on syn involving lifetimes returned by ChalkFlorian Diebold2021-04-091-0/+38
| | | | | | | | | | If we get lifetime variables back in autoderef, just immediately replace them by static lifetimes for now. Method resolution doesn't really deal correctly with new variables being introduced (this needs to be fixed more properly). This fixes `rust-analyzer analysis-stats --with-deps` crashing in the RA repo.

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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]>
