Macros

Introduction

Macros are a way to write code that writes other code. The term macro refers to a family of features in Rust: declarative macros with macro_rules! and three kinds of procedural macros:

• Custom #[derive] macros that specify code added with the derive attribute used on structs and enums
• Attribute-like macros that define custom attributes usable on any item
• Function-like macros that look like function calls but operate on the tokens specified as their argument
