Daniel Noom 998bf0ab88 Add note to non-exhaustive match on reference to empty ... Rust prints "type `&A` is non-empty" even is A is empty. This is the intended behavior, but can be confusing. This commit adds a note to non-exhaustive pattern errors if they are a reference to something uninhabited. I did not add tests to check that the note is not shown for non-references or inhabited references, because this is already done in other tests. Maybe the added test is superfluous, because `always-inhabited-union-ref` already checks for this case. This does not handle &&Void or &&&void etc. I could add those as special cases as well and ignore people who need quadruple references. Fixes #78123		2021-01-03 19:05:23 +01:00
