pub static IMPL_TRAIT_REDUNDANT_CAPTURES: &Lint
Expand description
The impl_trait_redundant_captures
lint warns against cases where use of the
precise capturing use<...>
syntax is not needed.
In the 2024 edition, impl Trait
s will capture all lifetimes in scope.
If precise-capturing use<...>
syntax is used, and the set of parameters
that are captures are equal to the set of parameters in scope, then
the syntax is redundant, and can be removed.
§Example
ⓘ
fn test<'a>(x: &'a i32) -> impl Sized + use<'a> { x }
{{produces}}
§Explanation
To fix this, remove the use<'a>
, since the lifetime is already captured
since it is in scope.
