m14-mental-model
Mental models and analogies for understanding Rust ownership, borrowing, and core concepts.
- Provides visual analogies (keys, lending, remotes) and mental models for ownership, moves, references, lifetimes, and smart pointers to build correct intuition
- Includes misconception-to-correction mappings for common borrow checker errors (E0382, E0502, E0499, E0106, E0507) with explanations of what safety guarantee each enforces
- Covers language-specific shifts for developers coming from Java, C++, Python, Go, and JavaScript, highlighting key differences in memory and mutability models
- Offers stack/heap and reference visualizations to clarify how ownership transfers and borrowing rules work in practice
Mental Models
Layer 2: Design Choices
Core Question
What's the right way to think about this Rust concept?
When learning or explaining Rust:
- What's the correct mental model?
- What misconceptions should be avoided?
- What analogies help understanding?
