2019-11-16Add regression test for issue 53820Nadrieril-0/+10
2019-11-16Introduce new FixedLenSlice constructorNadrieril-11/+11
It is used in the case where a variable-length slice pattern is used to match on an array of known size. This allows considering only those entries in the array that are captured by one of the patterns. As a side-effect, diagnostics improve a bit for those cases.

2019-11-05Use VarLenSlice consistently when splitting constructorsNadrieril-21/+21
The previous behaviour ignored slice lengths above a certain length because it could not do otherwise. We now have VarLenSlice however, that can represent the ignored lengths to make the algorithm more consistent. This does not change the correctness of the algorithm, but makes it easier to reason about. As a nice side-effect, exhaustiveness errors have improved: they now capture all missing lengths instead of only the shortest.
2019-11-05Add some test casesNadrieril-1/+31
2019-11-05Make exhaustiveness error message more consistent for slice patternsNadrieril-11/+11
This improves error messages by indicating when slices above a certain lengths have not been matched. Previously, we would only report examples of such lengths, but of course never all of them.
2019-11-05Don't use max_slice_length when subtracting from VarLenSliceNadrieril-2/+2
This alters error messages slightly, but that'll be improved later

2019-11-03Auto merge of #65759 - tmiasko:ui, r=petrochenkovbors-2/+2
Validate error patterns and error annotation in ui tests when present Previously, when compilation succeeded, neither error patterns nor error annotation would be validated. Additionally, when compilation failed, only error patterns would be validated if both error patterns and error annotation were present. Now both error patterns and error annotation are validated when present, regardless of compilation status. Furthermore, for test that should run, the error patterns are matched against executable output, which is what some of tests already expect to happen, and when #65506 is merged even more ui tests will. Fixes #56277
2019-11-02Update error annotations in tests that successfully compileTomasz Miąsko-2/+2
Those annotation are silently ignored rather than begin validated against compiler output. Update them before validation is enabled, to avoid test failures.

2019-10-27Gather together usefulness testsNadrieril-0/+2036
I took most tests that were testing only for match exhaustiveness, pattern refutability or match arm reachability, and put them in the same test folder.
2019-10-27Point at local similarly named element and tweak references to variantsEsteban Küber-2/+5
Point at the span for the definition of ADTs internal to the current crate. Look at the leading char of the ident to determine whether we're expecting a likely fn or any of a fn, a tuple struct or a tuple variant. Turn fn `add_typo_suggestion` into a `Resolver` method.

2019-09-24Remove blanket silencing of "type annotation needed" errorsEsteban Küber-15/+23
Remove blanket check for existence of other errors before emitting "type annotation needed" errors, and add some eager checks to avoid adding obligations when they refer to types that reference `[type error]` in order to reduce unneded errors.

2019-07-01Auto merge of #61682 - Centril:stabilize-type_alias_enum_variants, ↵bors-43/+0
r=petrochenkov Stabilize `type_alias_enum_variants` in Rust 1.37.0 Stabilize `#![feature(type_alias_enum_variants)]` which allows type-relative resolution with highest priority to `enum` variants in both expression and pattern contexts. For example, you may now write: ```rust enum Option<T> { None, Some(T), } type OptAlias<T> = Option<T>; fn work_on_alias(x: Option<u8>) -> u8 { match x { OptAlias::Some(y) => y + 1, OptAlias::None => 0, } } ``` Closes https://github.com/rust-lang/rfcs/issues/2218 Closes https://github.com/rust-lang/rust/issues/52118 r? @petrochenkov
