Macro pasts::exec

macro_rules! exec {
    ($e:expr $(,)?) => { ... };
    ($e:expr, $($f:expr),* $(,)?) => { ... };
}

Execute futures concurrently; in parallel if the target supports it, otherwise asynchronously.

Similar to poll!(), except that you can call it from synchronous code, and after calling it once, future calls will panic. The program will exit after the first future returns Poll::Ready. That means all threads and single-threaded executorr started by this macro will run for the remainder of the program, giving them a 'static lifetime.

Example

async fn async_main() {
    /* your code here */
}

// Note that you may add multiple concurrent async_main()s.
pasts::exec!(async_main());
