Provided Methods

unsafe fn invalidate(&self)

where Self: Sized + Message,

Called when the system wants to cancel a currently running enumeration, or when the system is finished using this enumerator object.

For instance, the user has changed their query, and the result of the currently running query will no longer be used by the system.

Or, the system is finished using this enumerator object.

The extension should cancel any outstanding requests and cleanup resources.

unsafe fn enumerateSearchResultsForObserver_startingAtPage( &self, observer: &ProtocolObject<dyn NSFileProviderSearchEnumerationObserver>, page: Option<&NSFileProviderPage>, )

where Self: Sized + Message,

Available on crate feature NSFileProviderEnumerating only.

Enumerate search results starting from the specified page.

• Parameters:
• observer: The observer object, which the extension will use to provide results.
• page: If a previous enumeration returned a nextPage on -[NSFileProviderSearchEnumerationObserver finishEnumeratingUpToPage:], the system may pass that page into the next enumeration. The page should contain whatever information is needed to resume the enumeration.
