I am happy to announce the release of BackON v1.4.0 via archive.is.

BackON is a rust library for making retry like a built-in feature provided by Rust.

use backon::ExponentialBuilder;
use backon::Retryable;

async fn fetch() -> Result<String> {
    Ok("hello, world!".to_string())
}

let content = fetch.retry(ExponentialBuilder::default()).await?;

The biggest change in this release was introduced by @wackazong, who correctly added std support for no-std without requiring a global random seed. With this improvement, users on no-std can now use jitter properly as well.

@NumberFour8 brought us futures-timer support, allowing backon to be used in an async context without relying on Tokio. @Matt3o12 contributed by making some functions const, enabling many backoff builder APIs to be used in a const context.

Thank you all!

As of the v1.4.0 release, BackON is now:

• Used by 1.1k projects on GitHub
• Has 39 reverse dependencies on crates.io
• Downloaded approximately 5 million times, averaging 20k downloads per day

Thank you all for your trust—let's make retries feel like a built-in feature in Rust!
