Bump exponential-backoff from 1.2.0 to 2.0.0

[dependabot]

Bumps exponential-backoff from 1.2.0 to 2.0.0.

Release notes

Sourced from exponential-backoff's releases.

v2.0.0

Overview

This release changes the type yielded by the iterator from Duration to Option<Duration>. This should simplify writing correct retry logic: after the last attempt there should never be an extra sleep.

This patch also changes the terminology: rather than counting retries, we're now counting total attempts. This makes it so that if you pass "3" as the number to the constructor, you'll now have a total of 3 attempts, rather than 1 attempt + 3 additional retries.

Finally: there is now also an implementation of IntoIterator for Backoff: that means if you're not reusing Backoff instances, you no longer have to pass the type by-reference:

use exponential_backoff::Backoff;
use std::{fs, thread, time::Duration};
let attempts = 3;
let min = Duration::from_millis(100);
let max = Duration::from_secs(10);
for duration in Backoff::new(attempts, min, max) { // ← Backoff passed by-value
match fs::read_to_string("README.md") {
Ok(string) => return Ok(string),
Err(err) => match duration {
Some(duration) => thread::sleep(duration),
None => return Err(err),
}
}
}
