Description
trait Bar {
type Item;
type Assoc: AsRef<[Self::Item]>;
}
struct Foo<T: Bar> {
t: <T as Bar>::Assoc,
}
impl<T: Bar<Item = u32>> Foo<T>
where
<T as Bar>::Assoc: AsRef<[u32]>,
{
fn hello(&self) {
println!("{}", self.t.as_ref().len());
}
}
fn main() {}Since <T as Bar>::Assoc can project to [u32] or <[T as Bar::Item]> (which is [u32]).
I found this in rand-core 0.5.x.
This is not present in the most recent rand-core version afaict, but many crates use rand-core 0.5.x as a dep.
