Overview of this book

Rust is a powerful language with a rare combination of safety, speed, and zero-cost abstractions. This Learning Path is filled with clear and simple explanations of its features along with real-world examples, demonstrating how you can build robust, scalable, and reliable programs. You’ll get started with an introduction to Rust data structures, algorithms, and essential language constructs. Next, you will understand how to store data using linked lists, arrays, stacks, and queues. You’ll also learn to implement sorting and searching algorithms, such as Brute Force algorithms, Greedy algorithms, Dynamic Programming, and Backtracking. As you progress, you’ll pick up on using Rust for systems programming, network programming, and the web. You’ll then move on to discover a variety of techniques, right from writing memory-safe code, to building idiomatic Rust libraries, and even advanced macros. By the end of this Learning Path, you’ll be able to implement Rust for enterprise projects, writing better tests and documentation, designing for performance, and creating idiomatic Rust code. This Learning Path includes content from the following Packt products: • Mastering Rust - Second Edition by Rahul Sharma and Vesa Kaihlavirta • Hands-On Data Structures and Algorithms with Rust by Claus Matzinger

thread-safety in Rust


In the previous section, we saw how the compiler stops us from sharing the data. If a child thread accesses data mutably, it is moved because Rust won't allow it to be used in the parent thread as the child thread might deallocate it, leading to a dangling pointer dereference in the main thread. Let's explore the idea of thread-safety and how Rust's type systems achieves that.

What is thread-safety?

thread-safety is the property of a type or a piece of code that, when executed or accessed by multiple threads, does not lead to unexpected behavior. It refers to the idea that data is consistent for reads while being safe from corruption when multiple threads write to it.

Rust only protects you from data races. It doesn't aim to protect against deadlocks as they are difficult to detect. It instead offloads this to third-party crates such as the parking_lot crate.

Rust has a novel approach to protecting against data races. Most of the thread-safety bits are already embedded...
