I think one of the more complex part of rust is async rust, especially when you need to go beneath the surface. So I'm always happy when I find good articles trying to clarify what is going on behind the scenes.

The hardest part (for me) is dealing with the type requirements for the handlers. 99% of the time a simple await is enough, but when it isn't, I feel like I need to go spelunking.

Especially dealing with those pinned structs for the state. I get why it's needed because it's on the stack somewhere but it sure makes it hard to work with without using pin_project or pin_project_lite.

Yeah I hope that will improve over time (maybe with the necessary ergonomic changes for async traits and higher kinded types). But I feel this is just a matter of time and will likely be much better after the next Rust edition
