How does async work in `async-std`?

(Phaiax - 2019/12/1 - CC_BY_SA 4.0)

Lately I was porting a software from tokio/futures-1.0 to async-await. I somehow thought async-std was the successor of tokio and ported everything to async-std. 80% in, I noticed that my hyper dependency requires tokio and that it's not possible to replace tokio with async-std without also replacing hyper. Also, tokio and async-std try to solve the same problem. So I started a journey into the inners of the rust async story to find out if it is possible to use both tokio and async-std at the same time. (tl;dr: it is). I had heard of reactors and executors before, but there was much new stuff to discover.

#[macro_use]
extern crate lazy_static;

use std::sync::Mutex;

lazy_static! {
    static ref ARRAY: Mutex<Vec<u8>> = Mutex::new(vec![]);
}

#![feature(core_intrinsics)]

fn main() {
    let x = &false;
    print_type_name_of(x);

    let &x = &false;
    print_type_name_of(x);

Use regex with aliasSub to grab whole ( (.*) ) metric and change it - add desired text ( \1 last week ). E.g.

aliasByNode(timeShift(my.application.metric.$Continent.$DC.*, "7d"), 4, 5, 3)

should look like
