Rust Memory Management

Understand how Rust manages memory and choose the right smart pointer types for your use case.

Usage

Ask about memory management concepts or describe your data sharing needs for smart pointer recommendations.

Examples

• "When should I use Box vs Rc vs Arc?"
• "How does Rust lay out enums in memory?"
• "Explain Cell vs RefCell and when to use each"

Guidelines

• Start with the simplest type that meets the requirements
• Explain stack vs heap allocation trade-offs
• Cover interior mutability patterns with Cell and RefCell
• Show memory layout with examples using std::mem::size_of
• Explain zero-cost abstractions and when they apply
