pub fn aggregate_by_name( &self, name: &str, arguments: Vec<&str>, ) -> Option<AggregateMeta>

Gets the aggregate metadata for the provided aggregate name.

pub fn table_iter(&mut self) -> TableIterator

Iterator over the tables in this keyspaces

pub fn function_iter(&mut self) -> FunctionIterator

Iterator over the functions in this keyspaces

pub fn user_type_iter(&mut self) -> UserTypeIterator

Iterator over the UDTs in this keyspaces

pub fn materialized_view_iter(&mut self) -> MaterializedViewIterator

Iterator over the materialized views in this keyspaces

pub fn name(&self) -> String
