Trait for database introspection

This trait abstracts database queries for schema introspection, allowing the schema cache to be tested without a real database connection.

Required Methods§

Source

fn query_tables<'life0, 'life1, 'async_trait>( &'life0 self, schemas: &'life1 [String], ) -> Pin<Box<dyn Future<Output = Result<Vec<TableRow>, Error>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Query all tables and views in the specified schemas

Source

fn query_relationships<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Vec<RelationshipRow>, Error>> + Send + 'async_trait>>
