Struct RetryConfig 

pub struct RetryConfig {
    pub max_attempts: u32,
    pub base_delay: Duration,
    pub max_delay: Duration,
    pub jitter: bool,
}

Retry policy configuration (truncated exponential backoff with jitter).

Under CacheKit::io, all attempts of one operation also share one deadline: 5 s for a read (get, exists) and 10 s for a write (set, delete), matching the cachekit.io backend’s per-attempt timeouts. An attempt still running at the deadline is cancelled and the operation fails with a Timeout error, and no backoff sleep starts that would end past it. A cachekit.io request that stops answering therefore costs one attempt, not max_attempts of them, while fast failures (a 503, a dropped connection) still get every attempt that fits. Other backends, and a backend set on the builder after io, get no deadline: their operations run to their own timeouts.

Fields

max_attempts: u32

Total attempts, including the first (default: 3). 0 behaves as 1.

base_delay: Duration

Backoff base delay; attempt n waits base_delay * 2^n (default: 100 ms).

max_delay: Duration

Backoff ceiling (default: 5 s).

jitter: bool

Multiply each delay by a random factor in [0.5, 1.5) (default: true).
