Async Rust doesn't have to be hard
I write a decent amount of Rust and I find it productive, but I can see how it might be easy to get nerd-sniped trying to get rid of every last allocation. There's no shame in a Box/Arc. Remember that almost every language puts almost everything on the heap. Just allocate. It'll be fine. Really.<p>I set a rule for myself that I'll spend up to one minute trying to save an allocation. Beyond that it's not worth getting sidetracked.
