2020-02-09Auto merge of #68689 - estebank:where-clause-sugg-missing-fn, r=varkorbors-1/+1
When suggesting associated fn with type parameters, include in the structured suggestion Address #50734. ``` error[E0046]: not all trait items implemented, missing: `foo`, `bar`, `baz` --> file.rs:14:1 | 14 | impl TraitA<()> for S { | ^^^^^^^^^^^^^^^^^^^^^ missing `foo`, `bar`, `baz` in implementation | = help: implement the missing item: `fn foo<T>(_: T) -> Self where T: TraitB, TraitB::Item = A { unimplemented!() }` = help: implement the missing item: `fn bar<T>(_: T) -> Self { unimplemented!() }` = help: implement the missing item: `fn baz<T>(_: T) -> Self where T: TraitB, <T as TraitB>::Item: std::marker::Copy { unimplemented!() }` ``` It doesn't work well for associated types with `ty::Predicate::Projection`s as we need to resugar `T: Trait, Trait::Assoc = K` → `T: Trait<Assoc = K>`.

2019-09-14Provide a span if main function is not present in crateMark Rousskov-1/+3
Unfortunately, the diagnotic machinery does not cope well with an empty span which can happen if the crate is empty, in which case we merely set a spanless note.

2019-03-02Point at enum definition when match patterns are not exhaustiveEsteban Küber-2/+10
``` error[E0004]: non-exhaustive patterns: type `X` is non-empty --> file.rs:9:11 | 1 | / enum X { 2 | | A, | | - variant not covered 3 | | B, | | - variant not covered 4 | | C, | | - variant not covered 5 | | } | |_- `X` defined here ... 9 | match x { | ^ | = help: ensure that all possible cases are being handled, possibly by adding wildcards or more match arms error[E0004]: non-exhaustive patterns: `B` and `C` not covered --> file.rs:11:11 | 1 | / enum X { 2 | | A, 3 | | B, 4 | | C, | | - not covered 5 | | } | |_- `X` defined here ... 11 | match x { | ^ patterns `C` not covered ``` When a match expression doesn't have patterns covering every variant, point at the enum's definition span. On a best effort basis, point at the variant(s) that are missing. This does not handle the case when the missing pattern is due to a field's enum variants: ``` enum E1 { A, B, C, } enum E2 { A(E1), B, } fn foo() { match E2::A(E1::A) { E2::A(E1::B) => {} E2::B => {} } //~^ ERROR `E2::A(E1::A)` and `E2::A(E1::C)` not handled } ``` Unify look between match with no arms and match with some missing patterns. Fix #37518.

This makes the capitalisation consistent and provides more context (especially for missing top-level attributes).

Do not point at the entire block span on fn return type mismatches caused by missing return.
2018-12-25Remove licensesMark Rousskov-186/+15
2018-11-07Removed `#[rustc_error]` from tests that are all `// compile-pass`.Felix S. Klock II-13/+5
I also added `// skip-codegen` to each one, to address potential concerns that this change would otherwise slow down our test suite spending time generating code for files that are really just meant to be checks of compiler diagnostics. (However, I will say: My preference is to not use `// skip-codegen` if one can avoid it. We can use all the testing of how we drive LLVM that we can get...) (Updated post rebase.)
