Function backoff::retry [−][src]
pub fn retry<F, B, T, E>(backoff: B, op: F) -> Result<T, Error<E>> where
F: FnMut() -> Result<T, Error<E>>,
B: Backoff,
Retries this operation according to the backoff policy. backoff is reset before it is used.
Examples
let f = || -> Result<(), Error<&str>> { // Business logic... // Give up. Err(Error::Permanent("error")) }; let backoff = ExponentialBackoff::default(); let _ = retry(backoff, f).err().unwrap();
