Enum AnyIntrospector 

pub enum AnyIntrospector {
    Postgres(PostgresIntrospector),
}

Enum dispatch for database introspectors.

Uses enum dispatch instead of Box<dyn DatabaseIntrospector> because the trait uses async_fn_in_trait and cannot be object-safe.

Variants

Postgres(PostgresIntrospector)

PostgreSQL introspector.

Trait Implementations

impl DatabaseIntrospector for AnyIntrospector

async fn list_fact_tables(&self) -> Result<Vec<String>>

List all fact tables in the database (tables starting with “tf_”).

async fn get_columns( &self, table_name: &str, ) -> Result<Vec<(String, String, bool)>>

Query column information for a table.

async fn get_indexed_columns(&self, table_name: &str) -> Result<Vec<String>>

Query indexes for a table.

fn database_type(&self) -> DatabaseType

Get database type (for SQL type parsing).

async fn get_sample_jsonb( &self, table_name: &str, column_name: &str, ) -> Result<Option<Value>>

Get sample JSONB data from a column to extract dimension paths.

async fn list_relations(&self) -> Result<Vec<RelationInfo>>

List all relations (tables and views) in the database.

async fn get_sample_json_rows( &self, table_name: &str, column_name: &str, limit: usize, ) -> Result<Vec<Value>>

Get sample JSON rows from a column for schema inference and the L3 JSONB-key drift check (#384).

async fn column_key_disagreements( &self, relation: &str, column: &str, json_column: &str, key: &str, limit: usize, ) -> Result<Option<(u64, u64)>>

Compare relation’s native column with the key of the same name in its json_column document, over at most limit rows (#1579): (sampled, disagreeing), a row disagreeing when to_jsonb(column) is distinct from json_column -> key (a row with neither agrees).

async fn function_exists( &self, schema: Option<&str>, name: &str, ) -> Result<Option<bool>>

Probe whether a callable SQL function named name exists — in schema when given, else resolved against the connection search_path.

async fn qualified_relation_exists( &self, schema: &str, name: &str, ) -> Result<Option<bool>>

Probe whether a schema-qualified relation exists, resolved case-sensitively / verbatim — the same way the runtime resolves a qualified sql_source (quote_postgres_identifier + to_regclass), so a mixed-case relation in an off-search_path schema is not falsely reported missing.

async fn get_view_definition(&self, relation: &str) -> Result<Option<String>>

The SQL body of relation, when it is a view (#1303).

async fn tview_declaration( &self, relation: &str, ) -> Result<Option<TviewDeclaration>>

The pg_tviews declaration of relation when it is a TVIEW’s table (#1571).

async fn is_tview(&self, relation: &str) -> Result<bool>

Whether relation is a table pg_tviews maintains, as its own catalog records it, whatever the relation is named.
