Since rust-lang/rust#54383 was merged the
FutureandStreamtraits have become object safe 🎉, here's a test playground showing thatPin<Box<dyn Future>>works.The only remaining reason for having
FutureObjexist is to support storing futures that are being spawned in custom "heap" allocations while keepingSpawna non-generic trait.I think
StreamObjcan probably be dropped, it seems likely that all current use-cases should work fine with using an explicit storage type,Box<dyn Stream>,Pin<Box<dyn Stream>>orSomeCustomHeapStore<dyn Stream>should all work, and if a user does need to be abstract over storage they likely already have some way to do this themselves.r? @cramertj
