Execution Tracking

In addition to automatically performing retries, Failsafe can be used to track executions for you, allowing you to manually retry as needed:

Execution execution = new Execution(retryPolicy);
while (!execution.isComplete()) {
  try {
    doSomething();
    execution.complete();
  } catch (ConnectException e) {
    execution.recordFailure(e);
  }
}

Execution tracking is also useful for integrating with APIs that have their own retry mechanism:

Execution execution = new Execution(retryPolicy);

// On failure
if (execution.canRetryOn(someFailure))
  service.scheduleRetry(execution.getWaitTime().toNanos(), TimeUnit.MILLISECONDS);

See the RxJava example for a more detailed implementation.
