ADBC: Arrow Database Connectivity
ADBC is a set of APIs and libraries for Arrow-native access to databases. Execute SQL and Substrait queries, query database catalogs, and more, all using Arrow data to eliminate unnecessary data copies, speed up access, and make it more convenient to build analytical applications.

The core library currently provides the basic types shared by vendor-specific drivers,
the driver manager, and the driver exporter.
§Native Rust drivers
Native Rust drivers will implement the abstract API consisting of the traits:
For drivers implemented in Rust, using these will be more efficient and safe, since it avoids the overhead of going through C FFI.
