pub static NON_CONTIGUOUS_RANGE_ENDPOINTS: &Lint
Expand description
The non_contiguous_range_endpoints
lint detects likely off-by-one errors when using
exclusive range patterns.
§Example
let x = 123u32;
match x {
0..100 => { println!("small"); }
101..1000 => { println!("large"); }
_ => { println!("larger"); }
}
{{produces}}
§Explanation
It is likely a mistake to have range patterns in a match expression that miss out a single
number. Check that the beginning and end values are what you expect, and keep in mind that
with ..=
the right bound is inclusive, and with ..
it is exclusive.
