the missing of cancellation token in Tokio is so infuriating. I have to came all the way to attach it to a Future.

the tokio::spawn() (the Rust async sucks function) won’t have to be complaining endlessly about lifetimes whenever you use a local variable.
Hacker News • HackerNews • Use case: Async runtime, specifically using tokio::spawn()
Rust async basically is tokio and it's almost impossible to use another runtime... In many ways Rust is the language that tokio ate.

Blocking on Tokio worker threads can quietly tank throughput and explode p99 latency, all without panics or anything obvious in the logs.
