Esteban Küber 8221f9c837 Account for ! arm in tail match expr ... On functions with a default return type that influences the coerced type of `match` arms, check if the failing arm is actually of type `!`. If so, suggest changing the return type so the coercion against the prior arms is successful. ``` error[E0308]: `match` arms have incompatible types --> $DIR/match-tail-expr-never-type-error.rs:9:13 | LL | fn bar(a: bool) { | - help: try adding a return type: `-> i32` LL | / match a { LL | | true => 1, | | - this is found to be of type `{integer}` LL | | false => { LL | | never() | | ^^^^^^^ | | | | | expected integer, found `()` | | this expression is of type `!`, but it get's coerced to `()` due to its surrounding expression LL | | } LL | | } | |_____- `match` arms have incompatible types ``` Fix #24157.		2023-11-27 16:19:02 +00:00
