Trait ILMessageFilterQueryHandling 

pub unsafe trait ILMessageFilterQueryHandling: NSObjectProtocol {
    // Provided method
    unsafe fn handleQueryRequest_context_completion(
        &self,
        query_request: &ILMessageFilterQueryRequest,
        context: &ILMessageFilterExtensionContext,
        completion: &DynBlock<dyn Fn(NonNull<ILMessageFilterQueryResponse>)>,
    )
       where Self: Sized + Message { ... }
}

Available on crate feature ILMessageFilterQueryHandling only.

Functionality related to MessageFilter extension query requests.

Subclasses of ILMessageFilterExtension which support querying must conform to this protocol.

Provided Methods

unsafe fn handleQueryRequest_context_completion( &self, query_request: &ILMessageFilterQueryRequest, context: &ILMessageFilterExtensionContext, completion: &DynBlock<dyn Fn(NonNull<ILMessageFilterQueryResponse>)>, )

where Self: Sized + Message,

Available on crate features ILMessageFilterExtensionContext and ILMessageFilterQueryRequest and ILMessageFilterQueryResponse and block2 only.

Evaluate a query request and provide a response describing how the system should handle the message it represents.

May include either (or both) of the following:

• Using offline/stored information to form a response about the message described by the query request.

• Deferring the query request to a network service associated with the app extension, allowing the network service to return data back to extension in order to form a response about the message. The context parameter provides an API which allows deferring a request to the network and receiving the response to that network request.

Block specified in completion parameter must be invoked with a response describing how to handle the message, and may be invoked asynchronously.

Parameter queryRequest: A query request to be handled which describes a received message.

Parameter context: Extension context which offers API to defer request to network if necessary.

Parameter completion: Completion block for returning a response.
