impl CatalogProviderList for DynamicFileCatalog

Source§

fn as_any(&self) -> &dyn Any

fn register_catalog( &self, name: String, catalog: Arc<dyn CatalogProvider>, ) -> Option<Arc<dyn CatalogProvider>>

Adds a new catalog to this catalog list If a catalog of the same name existed before, it is replaced in the list and returned.
Source§

fn catalog_names(&self) -> Vec<String>

Retrieves the list of available catalog names
Source§

fn catalog(&self, name: &str) -> Option<Arc<dyn CatalogProvider>>
