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.
