Rust's async model relies on Futures, but without an executor, they won't run! In this video, we demystify Rust's async execution, explaining why you need an executor and how it drives async tasks. You'll learn how popular executors like Tokio and async-std work under the hood and why Rust doesn't include a built-in executor. Finally, we'll walk through building a minimal custom executor, giving you a deeper understanding of Rust’s async runtime. Whether you're debugging async performance or optimizing concurrency, this is a must-watch!
