Retry with backoff without effort.
The opposite backoff implementation of the popular backoff.
- Newer: developed by Rust edition 2021 and latest stable.
- Cleaner: Iterator based abstraction, easy to use, customization friendly.
- Easier: Trait based implementations, works like a native function provided by closures.
Retry a blocking function.
use anyhow::Result;
use backon::BlockingRetryable;
use backon::ExponentialBuilder;
fn fetch() -> Result<String> {
Ok("hello, world!".to_string())
}
fn main() -> Result<()> {
let content = fetch.retry(&ExponentialBuilder::default()).call()?;
println!("fetch succeeded: {}", content);
Ok(())
}Retry an async function.
use anyhow::Result;
use backon::ExponentialBuilder;
use backon::Retryable;
async fn fetch() -> Result<String> {
Ok(reqwest::get("https://www.rust-lang.org").await?.text().await?)
}
#[tokio::main]
async fn main() -> Result<()> {
let content = fetch.retry(&ExponentialBuilder::default()).await?;
println!("fetch succeeded: {}", content);
Ok(())
