Example configuring exponential backoff?

[tobymurray]

I want a greater duration between the initial failure and the first retry. The docs show a lot of examples with ExponentialBackoff::default(), what's the recommended way to configure it? Is it sensible to do something like:

let backoff = ExponentialBackoff {
		initial_interval: std::time::Duration::from_secs(1),
		current_interval: std::time::Duration::from_secs(1),
		..Default::default()
	};

Does current_interval need to be set to the same value as initial_interval?

Not sure if better or worse, but the following also works:

let backoff = ExponentialBackoffBuilder::new()
    .with_initial_interval(std::time::Duration::from_secs(1))
    .build();

Either way, I agree that it would be best to have the correct (and least likely to break) approach documented.
