abstract struct Athena::ORM::Driver
inherits Struct
#
What the ORM needs to know about a crystal-db driver shard, beyond the API DB::Connection already shares across shards.
The ORM has one for each supported driver shard, picked by AORM::DriverManager from the name the shard registers its connections with (DB::Connection#driver_name).
