Ownership

The single-owner mental model, moves versus copies, the borrowing rules, and lifetimes as the compile-time bookkeeping that answers "how long does this reference stay valid."

Learn Rust ownership fundamentals through 10 examples, covering the single-owner rule, moves, scope, Drop, and ownership transfer.

Understand Rust's move and copy semantics. Learn when types move or copy, how to use Copy and Clone traits, and design APIs that manage ownership.

Learn how Rust's borrowing system works with shared &T and mutable &mut T references, including aliasing rules and reborrowing.

Understand the Rust borrow checker's logic, common errors like "borrowed value does not live long enough," and how to resolve them.

Understand Rust lifetimes, their syntax like 'a, and how they prevent dangling pointers. Learn to use them in function signatures and structs.

Learn how to use explicit lifetime annotations in Rust function signatures, structs, enums, and trait implementations.

Understand lifetime elision rules to omit explicit lifetime annotations in Rust function signatures, simplifying code while maintaining memory safety.

Design Rust APIs and data structures that work with the borrow checker. Learn rules for API shape, mutation, sharing, cloning, and copying.
