2019-10-27Gather together usefulness testsNadrieril-399/+0
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.
2019-08-06pretty-pretty extremal constants!Zack M. Davis-4/+4
While many programmers may intuitively appreciate the significance of "magic numbers" like −2147483648, Rust is about empowering everyone to build reliable and efficient software! It's a bit more legible to print the constant names (even noisy fully-qualified-paths thereof). The bit-manipulation methods mirror those in `librustc_mir::hair::pattern::_match::all_constructors`; thanks to the immortal Varkor for guidance. Resolves #56393.

2019-03-02Point at enum definition when match patterns are not exhaustiveEsteban Küber-10/+100
``` 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.
