FailurePolicy (Vert.x Stack - Docs 5.0.5 API)

All Superinterfaces:

Predicate<Future<T>>
```
public interface FailurePolicy<T>
extends Predicate<Future<T>>
```
A failure policy for the CircuitBreaker.
The default policy is to consider an asynchronous result as a failure if AsyncResult.failed() returns true. Nevertheless, sometimes this is not good enough. For example, an HTTP Client could return a response, but with an unexpected status code.
In this case, a custom failure policy can be configured with CircuitBreaker.failurePolicy(FailurePolicy).
