This lint detects and removes the unnecessary semicolon after a `match` or `if` statement returning `()`. It seems to be quite a common "mistake", given the number of hits (88) we had in the Clippy sources themselves. The lint doesn't bother about loops, as `rustfmt` already removes the extra semicolon. It doesn't handle blocks either, as an extra block level, followed or not by a semicolon, is likely intentional. I propose to put the lint in `pedantic`, as putting it in `style` seems quite hazardous given the number of hits. Note: there exists a `redundant-semicolon` lint in the compiler, but it is an early lint and cannot check that the expression evaluates to `()`, so it ignores the cases we're handling here. ---- changelog: [`unnecessary_semicolon`]: new lint |
