pub static BARE_TRAIT_OBJECTS: &Lint
Expand description
The bare_trait_objects
lint suggests using dyn Trait
for trait
objects.
§Example
ⓘ
trait Trait { }
fn takes_trait_object(_: Box<Trait>) {
}
{{produces}}
§Explanation
Without the dyn
indicator, it can be ambiguous or confusing when
reading code as to whether or not you are looking at a trait object.
The dyn
keyword makes it explicit, and adds a symmetry to contrast
with impl Trait
.
