Expand description
We also have to check the explicit predicates declared on the type.
ⓘ
struct Foo<'a, T> {
field1: Bar<T>
}
struct Bar<U> where U: 'static, U: Foo {
...
}
Here, we should fetch the explicit predicates, which
will give us U: 'static
and U: Foo
. The latter we
can ignore, but we will want to process U: 'static
,
applying the substitution as above.
