Provided Methods

unsafe fn controller_didChangeContentWithDifference( &self, controller: &NSFetchedResultsController, diff: &NSOrderedCollectionDifference<NSManagedObjectID>, )

where Self: Sized + Message,

Available on crate features NSFetchRequest and NSManagedObjectID only.

Safety

controller generic should be bound by NSFetchRequestResult.

unsafe fn controller_didChangeObject_atIndexPath_forChangeType_newIndexPath( &self, controller: &NSFetchedResultsController, an_object: &AnyObject, index_path: Option<&NSIndexPath>, type: NSFetchedResultsChangeType, new_index_path: Option<&NSIndexPath>, )

where Self: Sized + Message,

Available on crate feature NSFetchRequest only.

Safety

• controller generic should be bound by NSFetchRequestResult.
• an_object should be of the correct type.

unsafe fn controller_didChangeSection_atIndex_forChangeType( &self, controller: &NSFetchedResultsController, section_info: &ProtocolObject<dyn NSFetchedResultsSectionInfo>, section_index: NSUInteger, type: NSFetchedResultsChangeType, )

where Self: Sized + Message,

Available on crate feature NSFetchRequest only.

Safety

controller generic should be bound by NSFetchRequestResult.

unsafe fn controllerWillChangeContent( &self, controller: &NSFetchedResultsController, )

where Self: Sized + Message,

Available on crate feature NSFetchRequest only.

Safety

controller generic should be bound by NSFetchRequestResult.

unsafe fn controllerDidChangeContent( &self, controller: &NSFetchedResultsController, )

where Self: Sized + Message,

Available on crate feature NSFetchRequest only.

Safety

controller generic should be bound by NSFetchRequestResult.

unsafe fn controller_sectionIndexTitleForSectionName( &self, controller: &NSFetchedResultsController, section_name: &NSString, ) -> Option<Retained<NSString>>

where Self: Sized + Message,

Available on crate feature NSFetchRequest only.

Safety

controller generic should be bound by NSFetchRequestResult.

Trait Implementations

where T: ?Sized + Message + NSFetchedResultsControllerDelegate,

impl ProtocolType for dyn NSFetchedResultsControllerDelegate

const NAME: &'static str = "NSFetchedResultsControllerDelegate"

fn protocol() -> Option<&'static AnyProtocol>

Get a reference to the Objective-C protocol object that this type represents.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
