Remember what I told you about the stars?
Of course β€” you said Polaris is your favorite because it helped you navigate on that camping trip in Norway. You also mentioned wanting to see the northern lights someday.
🧠 Memory saved: loves stargazing, northern lights

Learning Rust
πŸ’» Code Mentor
Explain ownership in Rust like I know Python
Think of it this way: in Python, variables are labels on boxes. You can stick multiple labels on the same box.

In Rust, each box has exactly one owner. When you assign it to a new variable, the old label gets ripped off. That's a move.
