Struct MemoryDatabase 

pub struct MemoryDatabase { /* private fields */ }

In-memory database implementation for testing and development.

This provides a simple in-memory store that implements the SchemaDatabase trait without requiring external database dependencies. Useful for:

• Testing
• Development
• Small-scale applications
• Temporary storage
