source ·




The path_statements lint detects path statements with no effect.
The unused_allocation lint detects unnecessary allocations that can be eliminated.
The unused_braces lint detects unnecessary braces around an expression.
The unused_import_braces lint catches unnecessary braces around an imported item.
The unused_must_use lint detects unused result of a type flagged as #[must_use].
The unused_parens lint detects if, match, while and return with parentheses; they do not need them.
The unused_results lint checks for the unused result of an expression in a statement.


Used by both UnusedParens and UnusedBraces to prevent code duplication.
