Trait Implementations§

Source §

impl CatalogList for GlobalCatalogs

Source §

fn as_any(&self) -> &dyn Any

Returns the catalog list as Any so that it can be downcast to a specific implementation.

Source §

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>>

Retrieves a specific catalog by name, provided it exists.
