Extensible, asynchronous retry behaviours based on futures, for the ecosystem of tokio libraries.
Add this to your Cargo.toml
:
[dependencies]
tokio-retry = "0.2"
extern crate futures;
extern crate tokio;
extern crate tokio_retry;
use futures::Future;
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 retry_strategy = ExponentialBackoff::from_millis(10)
.map(jitter)
.take(3);
let future = Retry::spawn(retry_strategy, action).then(|result| {
println!("result {:?}", result);
Ok(())
});
tokio::run(future);
}
