“Guide to Rustc Development” The Rust programming language is a modern, safe, and concurrent language that is designed to be fast, efficient, and maintainable. It is a compiled language, with a focus on performance and safety. It offers memory safety without the need for garbage collection, making it ideal for embedded and low-level development.

To get started with Rust, you will need to install the Rust compiler (rustc) and associated tools. The Rust compiler can be installed via the official installer or from a package manager like Homebrew. Once installed, you can use rustc to compile your Rust programs.

The next step is to learn the basics of Rust by reading some tutorials and examples. There are plenty of resources available online that can help you get up to speed with the language. You can also find helpful books and online courses available for those looking to dive deeper into the language.

Once you have a basic understanding of Rust, you can start writing your own programs. To do this, you will need to write code in an editor (e.g., Visual Studio Code or Atom) or an IDE (e.g., IntelliJ). After writing your code, you will need to compile it with rustc before running it on your machine. This process is called “building” in Rust parlance.

Finally, if you plan on contributing to the open source community, you should familiarize yourself with the rustc development process and guidelines outlined in the guide to rustc development blog post series linked above. This will help ensure your contributions are accepted by the community and that your code meets their standards for quality and style.


Rustc is the Rust compiler, and it is a powerful tool for making sure your Rust code is up to standard. With rustc, you can check for syntax and type errors, as well as run tests that verify that your code works as expected.

To get started with rustc, you need to download the latest version of the compiler from the official Rust website. Once it’s installed, you can start writing Rust code in any text editor and compile it with rustc.

To compile a program, use the command line command ‘rustc ’. This will create an executable file with the same name as the original file in the same directory. After compilation, you can run your program with ‘./’.

When running rustc, you can also use a number of flags to customize your compilation process. For example, ‘–warn’ will show warnings about possible problems in your code; ‘–release’ will compile your code more aggressively for a better performance; and ‘-L ’ will add a library path to look for dependencies when linking.

You can also use rustc in combination with other tools like cargo to build complex projects. Cargo provides features like dependency management and building multiple projects at once. To use cargo, simply run ‘cargo build’ instead of ‘rustc ’.

rustc is an essential part of writing Rust programs, and understanding how it works can help you write better code and debug more easily. With this guide to rustc development in mind, you should now have all the tools necessary to start developing Rust projects on your own!
