Macro usage in the Rust programming language in open source repositories

Abstract

This work presents an analysis of macro usage in the 100 most popular open-source Rust projects hosted on GitHub. The study aims to uncover patterns in the use of macros, which play a critical role in the Rust ecosystem by providing metaprogramming capabilities and improving code efficiency. By scraping project repositories, we identify the types of macros most frequently employed, analyze which projects rely heavily on macros, and delve into specific categories to determine the most commonly used macros. The results offer valuable insights into macro adoption trends in the Rust community and may assist developers in understanding how and why macros are applied in large-scale projects.
