What Is Rust?
One of the main reasons why Rust is so popular is its speed and performance. Rust is a compiled language, which means that the code is compiled into machine code that can run directly on the hardware. This makes Rust programs extremely fast and efficient.

A Great Way To Learn Rust
- Small scope: Command-line utilities are typically small projects that do one thing well. This makes them a great way to practice Rust programming without getting overwhelmed by a large codebase or complex project requirements.
- Real-world applications: Command-line utilities are often used in real-world scenarios, which means that building them provides an opportunity to learn how to solve practical problems with Rust. This can be a great way to build your confidence and competence as a Rust developer.
- Immediate feedback: With command-line utilities, you can quickly see the results of your code changes by running the utility and seeing the output. This provides immediate feedback on the correctness and effectiveness of your code, which can be very motivating.
- Low barrier to entry: Building command-line utilities requires only basic knowledge of Rust syntax and some familiarity with the standard library. This makes it a great way for beginners to get started with Rust programming.
- Fun and creative: Building command-line utilities can be a fun and creative way to practice Rust programming, as you can choose projects that interest you and solve problems that you find personally relevant.
