A Practical Introduction to Declarative Macros in Rust

In this video, we'll give you a practical introduction to declarative macros in Rust. We'll start with a simple example to help you understand what declarative macros are and how they can be written. We'll then explore positional, infinite positional, and named parameters in declarative macros, as well as fragment specifiers of parameters. By the end of this video, you'll have a solid understanding of declarative macros in Rust and how you can use them to make your code more concise and maintainable. To learn more about macros in Rust, check out the Macros section in the Rust Book at https://doc.rust-lang.org/book/ch19-0.... For more information on declarative macros specifically, you can also refer to the Declarative Macros reference at https://doc.rust-lang.org/reference/m....
