Database storage trait for symbol tables.

Implementations handle the specifics of different database backends.

Required Methods

fn store_schema( &mut self, name: &str, table: &SymbolTable, ) -> Result<SchemaId, AdapterError>

Store a complete symbol table in the database.

If a schema with the same name exists, it is updated.

fn load_schema(&self, id: SchemaId) -> Result<SymbolTable, AdapterError>

Load a symbol table by schema ID.

fn load_schema_by_name(&self, name: &str) -> Result<SymbolTable, AdapterError>

Load a symbol table by name (returns most recent version).

fn list_schemas(&self) -> Result<Vec<SchemaMetadata>, AdapterError>

List all available schemas.

fn delete_schema(&mut self, id: SchemaId) -> Result<(), AdapterError>

Delete a schema by ID.

fn search_schemas( &self, pattern: &str, ) -> Result<Vec<SchemaMetadata>, AdapterError>

Search schemas by name pattern.

fn get_schema_history( &self, name: &str, ) -> Result<Vec<SchemaVersion>, AdapterError>

Get schema history (all versions).
