tool-retry-policy

Declarative retry policy primitive. Tells you Retry(duration) or GiveUp; you run the actual call. Exponential backoff, deterministic jitter, per-policy attempt cap.

use tool_retry_policy::{Policy, Decision};
use std::time::Duration;
let p = Policy::default();
match p.next(2) {
    Decision::Retry(d) => println!("sleep {d:?}"),
    Decision::GiveUp => {},
}
