pub static OVERLAPPING_RANGE_ENDPOINTS: &Lint
Expand description
The overlapping_range_endpoints
lint detects match
arms that have range patterns that
overlap on their endpoints.
§Example
let x = 123u8;
match x {
0..=100 => { println!("small"); }
100..=255 => { println!("large"); }
}
{{produces}}
§Explanation
It is likely a mistake to have range patterns in a match expression that overlap in this
way. Check that the beginning and end values are what you expect, and keep in mind that
with ..=
the left and right bounds are inclusive.
