Arc doesn't allow storing unsized (trait objects) #147

Closed seanmonstar closed 2 years ago

seanmonstar commented 4 years ago

The loom::sync::Arc type needs to add T: ?Sized to allow Arc<dyn Any>.

It's mostly just adding bounds, but it does mean into_raw and from_raw need to be carefully adjusted, since ?Sized types need to be the last field on Inner.

But we don't get compiler coersion. So there is no clear way to do it. We could add additional fns.

Fixed in #226
