Provided Methods

unsafe fn didEnumerateSearchResults( &self, search_results: &NSArray<ProtocolObject<dyn NSFileProviderSearchResult>>, )

where Self: Sized + Message,

unsafe fn finishEnumeratingUpToPage( &self, next_page: Option<&NSFileProviderPage>, )

where Self: Sized + Message,

Available on crate feature NSFileProviderEnumerating only.

Call this method after enumerating a full page of results. If you set a non-nil nextPage, -[NSFileProviderSearchEnumerator enumerateSearchResultsToObserver:startingAtPage:] might be called with nextPage to enumerate more items.

Page data is limited to 500 bytes. Setting a larger nextPage interrupts the enumeration.

unsafe fn finishEnumeratingWithError(&self, error: &NSError)

where Self: Sized + Message,

Finishing a search enumeration with an error will cause the system to stop requesting additional pages of results. The system will not retry in case of an error. It is up to the extension to decide whether to retry errors internally, in their implementation of enumerateSearchResultsForObserver, or to return the error to the system and end the search query.

unsafe fn maximumNumberOfResultsPerPage(&self) -> NSInteger

where Self: Sized + Message,

The maximum number of results to return in a single page enumeration.

If the extension returns more than this number of results in a single page enumeration, the system will crash the extension process.
