(apply Predicate, opts ...Option)

// Filter emits only those items from an Observable that pass a predicate test.
func (s *SingleImpl) Filter(apply Predicate, opts ...Option) OptionalSingle {
	return optionalSingle(s.parent, s, func() operator {
		return &filterOperatorSingle{apply: apply}
	}, true, true, opts...)
}

// Get returns the item. The error returned is if the context has been cancelled.
// This method is blocking.
