code: @Override
      public Try<T> filter(Predicate<T> predicate) {
          return predicate.test(value) ? this : new Failure<>(new NoSuchElementException("Predicate did not match value, now empty result"));
      }
docs: Applies the predicate to the value of this instance, if it matches <i>this</i> is returned else a {@link Failure}.
