Pedantic Clippy

One of the reasons developers love Rust is its well-developed ecosystem. Clippy, a linter for the Rust code, is one of the main components in this ecosystem. It performs additional checks of the developed code reporting found issues and explaining how to fix them (and sometimes it even can fix them automatically). Its usage may be beneficial for Rust beginners and even professionals. In this article, I describe this tool and explain how to start using it.

Rust-Based Utilities

Rust has been recently named as the most loved language on Stackoverflow one more time. Currently it is not widely used in professional development, therefore developers often develop small programs to try it out. One obvious choice for these programs are different command line utilities, thus the number of such tools developed in Rust constantly grows. On, there is even a separate category devoted to these programs. Therefore, I have decided to write an article about the utilities I find useful in order to have their list in one place. I plan to update this article as I try more utils.

Closures in Rust

Today, I want to note down my thoughts on closures. Closures are important in Rust, because they are extensively used in iterator adapters paramount in development highly performant programs. However, to my point of view this topic is not well-covered in The Book. This may be a reason why it is considered among the most difficult parts of the language. In this post, I will try to shed more light on it, hopefully making it more clear to Rust learners. Note that I am still a novice to the language, and my understanding may not be fully correct.

Minimal Rust Binary Project

When you develop your first binary application using new language, the first issue that you face is how to organize your code so that you can easily extend it in the future. There is a good example in The Book on how to organize your code, parse and process command line arguments by yourself. However, in real world you would use a library to parse command line arguments, which most probably would be the clap library in case of Rust. In this article, I describe my template for creating a CLI (command line interface) application.
