## Concurrency in Rust Alex Crichton ## What's Rust? Rust is a systems programming language that runs blazingly fast, prevents segfaults, and guarantees thread safety. ## Concurrency? Rust? Libraries Libraries Futures ## What's concurrency? In computer science, concurrency is a property of systems in which several computations are executing simultaneously, and potentially interacting with each each other. ## Why concurrency?  ## Getting our feet wet // What does this print? int main() { int pid = fork(); p

## Back to Basics: Concurrency I also do C++ training! arthur.j.odwyer@gmail.com ## Outline - What is a data race and how do we fix it? [3–12] • C++11 mutex and RAI lock types [13–23] Questions? • • The blue/green pattern [46–52] ● Bonus C++20 slides [53–58] Questions? ## What is concurrency? - Concurrency means doing two things concurrently — “running together.” Maybe you’re switching back and music - In extremely broad strokes, parallelism is a hardware problem (think multiple CPUs) and concurrency is a software problem (think time-sharing, but also Intel’s “hyperthreading”). ## Why does C++

In this talk we provide a gentle introduction to concurrency with the modern C++ std::thread library. We will introduce topics with pragmatic code examples locks, and showing how these programming primitives enable concurrency. In addition, we will show the common pitfalls to be aware of with concurrency: data races, starvation, and deadlock (the most extreme
