Intro to Rust Async Function Execution With Smol 🦀 Rust Programming Tutorial for Developers

The Rust standard crate includes support for defining async functions. Rust async functions return a "Future" type, instead of a direct value. Although you can declare async functions, Rust doesn't include an executor to "drive" those Futures to completion. We need to either develop our own executor (advanced) or use a pre-built executor like tokio, smol, actix, or potentially others. In this video, we'll better understand how async programming works, and contrast it with synchronous and multi-threaded execution. By the end of this video, you should be able to understand how to define an async function and use "smol" as your async executor.
