Abstract APIs

This module provides various abstractions for reuse, mainly:

1. Protocols.

2. Type Aliases.

3. Type Guards.

4. An import Prelude.

5. A JGDVError class.

Protocols

Some General and more specific protocols. Also some protocol adaptions of the stdlib.

Type Aliases

Rather than str | None, I prefer Maybe[str]. Similarly Result[str, IndexError] etc.

Prelude
