Struct FnProvider 

pub struct FnProvider<F> { /* private fields */ }

A SearchProvider built from a closure plus its kind label — the convenient way to register a source without declaring a struct. Created via SearchRegistry::register_fn.

Implementations

impl<F> FnProvider<F>

pub fn new(name: impl Into<String>, f: F) -> FnProvider<F>

Trait Implementations

impl<F> SearchProvider for FnProvider<F>

where F: Fn(&str) -> Vec<SearchResult>,

fn name(&self) -> &str

The kind label this provider produces, used for diagnostics and as the default group header. Individual results may still carry a different SearchResult::kind.

fn search(&self, query: &str) -> Vec<SearchResult>

Return the matching results for query. An empty query conventionally returns a provider’s “browse” set (recents / favourites / all), or an empty vec if browsing makes no sense for the source.

fn action_directory_generation(&self) -> Option<u64>

Monotonic retained-index generation for the broker pull directory. None means the provider has not proved that a continuation cursor is safe across mutation, so remote directory discovery must omit it rather than silently advertise mutable rows as revision-stable. Providers backed by SearchCatalog should return Some(catalog.stats().generation).

fn action_directory_invocation_domain(&self) -> ActionDirectoryInvocationDomain

Versions this actual provider’s complete lazy invocation domain, including hidden targets and argument/handler semantics omitted from search rows.

fn action_directory_cursor_is_current(&self, _cursor: &SearchCursor) -> bool

Validate a continuation token before it is used by a remote pull directory. The conservative default refuses it: only providers that expose a retained generation may claim continuation safety.

fn search_limited(&self, query: &str, limit: usize) -> Vec<SearchResult>

Query with a materialisation budget. App providers must override this and stop constructing hits once limit is reached. The fallback exists only for tiny/test providers outside apps/; the repository contract checker rejects app implementations that inherit it.

fn search_page( &self, query: &SearchQuery, cursor: Option<&SearchCursor>, work_budget: usize, result_limit: usize, ) -> SearchPage

Return one bounded continuation page for an interactive search.

fn poll_page(&self, _token: &PendingToken) -> PagePoll

The page a SearchPage::pending token stands for, once its source has answered. Called on later frames, never in a loop; return PagePoll::Pending until the answer is in. A token the provider no longer knows (the query moved on) answers an empty ready page.

fn facets(&self) -> Vec<Facet>

The dimensions this provider filters by. The palette offers their values as chips and parses typed key:value tokens for them into SearchQuery::filters.

fn search_scopes(&self) -> Vec<ScopeDecl>

The parts of the app this provider’s hits can be narrowed to (see ScopeDecl). An unscoped palette offers each as a “Search in” row that narrows the search to it.

fn resolve_action_resource(&self, _address: &ActionAddress) -> Option<Resource>

Lazily resolve a canonical search address that is intentionally absent from the small open-resource snapshot.
