Getting in and out of trouble with Rust futures
Jul 07, 2020

I started experimenting with asynchronous Rust code back when futures 0.1
was all we had - before async/await. I was a Rust baby then (I’m at least
a toddler now), so I quickly drowned in a sea of .and_then, .map_err
and Either<A, B>.
But that’s all in the past! I guess!
Now everything is fine, and things go smoothly. For the most part. But even
with async/await, there are still some cases where the compiler diagnostics are,
just, so much.
