Description
I tried this code:
use std::collections::HashMap;
trait Example {}
struct Map<K, V>(HashMap<K, V>);
impl<K, V> Map<K, V>
where
HashMap<K, V>: Clone,
HashMap<String, V>: Example,
{
}
I get the warning
warning: this type has already been used as a bound predicate
--> src/main.rs:14:5
|
14 | HashMap<String, V>: Example,
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
= note: `-W clippy::type-repetition-in-bounds` implied by `-W clippy::pedantic`
= help: consider combining the bounds: `HashMap<String, V>: Clone + Example`
= help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#type_repetition_in_bounds
HashMap<K, V>
and HashMap<String, V>
are different types so this lint should not show.
