Enum Progress 

pub enum Progress {
    Send(HttpRequest),
    Wait(Duration),
    Done(Box<ExecutionReport>),
}

What the engine wants next.

Deliberately not #[non_exhaustive]: a driving loop must handle every variant, and a new one would have to break that loop to mean anything — so a catch-all arm would hide the very change it was there to absorb.

Variants

Send(HttpRequest)

Perform this request, then hand the response to Run::supply.

Wait(Duration)

Wait this long — a retry asked for it — then carry on.

Done(Box<ExecutionReport>)

The run is over.
