Trait VNFaceObservationAccepting 

pub unsafe trait VNFaceObservationAccepting: NSObjectProtocol {
    // Provided methods
    unsafe fn inputFaceObservations(
        &self,
    ) -> Option<Retained<NSArray<VNFaceObservation>>>
       where Self: Sized + Message { ... }

       where Self: Sized + Message { ... }
}

Available on crate feature VNFaceObservationAccepting only.

A protocol that allows a user to provide an input collection of VNFaceObservations as part of a request. The protocol can be adopted by request objects that request additional information about detected faces, such as facial landmarks.
