Yeah and I was trying to implement their workaround for missing dynamic dispatch in a generic-heavy multithreaded async (tokio, hyper) context.., Cfr: https://github.com/plabayo/tower-async/pull/12 https://github.com/plabayo/tower-async/pull/12 So far didn’t manage to produce a box that works without everything else in my tower async stack having to need send sync trait bounds as well… and of course needing nightly ‘call(): Send’ return bounds. Despite that, haven’t found a reasonable working solution to support that in ‘tower-async’ Might be just me still having to b learn a lot. More then happy to hear feedbacks add help on these matters. And of course this is a WIP. So fully understand. Respect to the entire async wg team. Onwards and forward.
