Macro debugging techniques
- [Instructor] Hey there. Last time we looked at async code in Rust. Today we are talking about macros. Macros are great for reusable code, but they can be hard to debug. Why? Because they expand at compile time. That means error messages can be confusing, and regular debugging don't always help. In this video, we'll use AI tools to help us debug Rust macros. Let's start with a simple macro, find this problem, and make it better. Let's get started. Before we look at the code, let me explain something real quick. In Rust macros, you'll see things like name:ident. The ident part means identifier. It's just a placeholder for name like user, or name, or anything. It tells the macro what to call your structs or fields. As we've seen the example, here's a basic macro that builds a struct with one field. Let's break it down. Name:ident is a struct name just like user. Field:ident is a field name like name. This creates a struct with one string feed, but there's a problem. It only works with…
