Struct RetryPolicy 

pub struct RetryPolicy {
    pub max_retries: u32,
    pub base_delay: Duration,
    pub backoff_factor: f64,
}

Exponential back-off policy for retrying gap-fetch Interests.

The reference ndnSVS implementation retries up to 4 times with a 2× backoff starting at 1 second. Pass a RetryPolicy to fetch_with_retry to apply these semantics to your own fetch logic.

Example

use ndn_sync::RetryPolicy;

let data = fetch_with_retry(RetryPolicy::default(), || async {
    consumer.fetch("/ndn/svs/alice/1").await
}).await?;

Fields

max_retries: u32

Maximum number of retry attempts after the first failure (default: 4).

base_delay: Duration

Delay before the first retry (default: 1 s).

backoff_factor: f64

Multiplier applied to the delay after each attempt (default: 2.0).
