source · 
pub(crate) static UNUSED_PARENS: &Lint
Expand description

The unused_parens lint detects if, match, while and return with parentheses; they do not need them.

Examples

if(true) {}

{{produces}}

Explanation

The parentheses are not needed, and should be removed. This is the preferred style for writing these expressions.
