8 Asynchronous Programming

Asynchronous programming is, as the name implies, programming that is not synchronous. At a high level, an asynchronous operation is one that executes in the background—the program won’t wait for the asynchronous operation to complete but will instead continue to the next line of code immediately. If you’re not already familiar with asynchronous programming, that definition may feel insufficient as it doesn’t actually explain what asynchronous programming is. To really understand the asynchronous programming model and how it works in Rust, we have to first dig into what the alternative is. That is, we need to understand ...
