Extensible, asynchronous retry behaviours based on futures, for the ecosystem of tokio libraries.
Add this to your Cargo.toml
:
[dependencies]
tokio-retry = "0.1"
extern crate tokio_core;
extern crate tokio_retry;
use tokio_core::reactor::Core;
use tokio_retry::Retry;
use tokio_retry::strategy::{ExponentialBackoff, jitter};
fn action() -> Result<u64, ()> {
// do some real-world stuff here...
Ok(42)
}
fn main() {
let mut core = Core::new().unwrap();
let retry_strategy = ExponentialBackoff::from_millis(10)
.map(jitter)
.take(3);
let retry_future = Retry::spawn(core.handle(), retry_strategy, action);
let retry_result = core.run(retry_future);
assert_eq!(retry_result, Ok(42));
}
