Function drive_fn 

Source 
pub fn drive_fn<A, F>(f: F) -> AsyncFnDriver<F, A>
where
    A: for<'a> Arbitrary<'a>,
    F: AsyncFnMut(A) -> ControlFlow<()>,
Expand description

Construct a Driver from an AsyncFnMut.

Use this when the driver needs .await (e.g. tx.send(item).await).

The async function receives an arbitrary argument and returns ControlFlow<()>:

  • ControlFlow::Continue(()) - progress made, future should be polled
  • ControlFlow::Break(()) - driver is done
