Trait CLSContextProvider 

pub unsafe trait CLSContextProvider {
    // Provided method
    unsafe fn updateDescendantsOfContext_completion(
        &self,
        context: &CLSContext,
        completion: &DynBlock<dyn Fn(*mut NSError)>,
    )
       where Self: Sized + Message { ... }
}

Available on crate feature CLSContextProvider only.

The CLSContext provider protocol.

The app extension that provides CLSContexts should adopt this protocol.

Provided Methods

unsafe fn updateDescendantsOfContext_completion( &self, context: &CLSContext, completion: &DynBlock<dyn Fn(*mut NSError)>, )

where Self: Sized + Message,

Available on crate features block2 and CLSContext and CLSObject only.

This method asks the app extension to update CLSContexts that are descendants of a given context.

Parameter context: A CLSContext whose descendants are to be updated

Parameter completion: A completion block the extension should call with an optional error to indicate success or failure.

The extension may choose to modify, delete, or create some or all descendants of the given context. The host app may call this method as the user selects a context.
