Rust Coding Standards

Purpose: Master Rust's ownership system, type safety, and zero-cost abstractions for building safe, concurrent, and performant systems.

Level 1: Quick Reference

Core Principles

• Ownership: Each value has exactly one owner
• Borrowing: References allow multiple readers XOR one writer
• Zero-cost abstractions: High-level code compiles to optimal machine code
• Explicit over implicit: No hidden allocations or control flow

Ownership & Borrowing Cheat Sheet

// Ownership transfer (move)
let s1 = String::from("hello");
let s2 = s1; // s1 is now invalid
