CircuitFailurePredicate class abstract

Predicate that decides whether a failure counts for the circuit breaker.

Callers can extend this class or use CircuitFailurePredicate.where to provide domain-specific circuit failure classification.

Inheritance

Constructors

CircuitFailurePredicate()

Counts ordinary exception outcomes except cancellation.
factory
CircuitFailurePredicate.exceptionWhere(FutureOr<bool> test(Object error, StackTrace stackTrace))
Counts exception outcomes matching test.
factory
