Borrowing

Borrowing is a memory safety mechanism in Rust that allows multiple references to data without transferring ownership, preventing data races and ensuring compile-time safety. It enforces rules where references can be either mutable or immutable, but not both simultaneously, to avoid conflicts. This concept is central to Rust's approach to managing memory without a garbage collector.

Also known as: Rust Borrowing, Borrow Checker, Ownership and Borrowing, Reference Rules, Lifetimes

Why learn Borrowing?

Developers should learn borrowing when working with Rust to write safe, concurrent code without runtime overhead, as it prevents common bugs like use-after-free and data races. It is essential for systems programming, embedded development, and performance-critical applications where manual memory management is required but safety is paramount. Understanding borrowing helps leverage Rust's zero-cost abstractions effectively.
