Whoa, very cool! Can’t wait for 1.75.
-> impl Trait in public traits
That’s a bummer. This works:
trait Base { fn op(&self); } trait Child : Base { fn other_op(&self); } trait A { fn some_fn(val: impl Base) { val.op(); } } fn some_fn(val: impl Child) { val.op(); val.other_op(); }
So it seems like returning an
impl Child
in a trait that bindsimpl Base
should also work.Hopefully this change means we’ll see more of this kind of thing in the upcoming releases.
