Optional backend extension for online backup.

Safety

Implementations must return backup handles tied to the provided database handles and honor SQLite’s backup lifecycle requirements.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
