source static INVALID_NAN_COMPARISONS: &Lint
Expand description
The invalid_nan_comparisons
lint checks comparison with f32::NAN
or f64::NAN
as one of the operand.
§Example
let a = 2.3f32;
if a == f32::NAN {}
{{produces}}
§Explanation
NaN does not compare meaningfully to anything – not
even itself – so those comparisons are always false.
