Function direct_executor::run

pub fn run<F>(future: F, wait: impl FnMut()) -> F::Output where
    F: Future, 

Runs the provided future until polling succeeds, calling the provided wait closure in between each polling attempt.

A common pattern is to let wait simply be some delay function (like sleep()), or in certain environments (such as on embedded devices), it might make sense to call wfi to wait for peripheral interrupts, if you know that to be the source of future completion.
