🚀 My Journey with Rust! 🦀

During the past month, I have spent time learning Rust. Rust is a statically-typed programming language known for its focus on safety, performance, and concurrency. It provides memory safety guarantees without sacrificing performance, thanks to its ownership model, borrowing system, and strict compile-time checks. Rust is designed for building reliable and efficient systems, empowering developers to write high-quality, concurrent code that is resistant to common programming errors.

What intrigued me to learn this language is because Rust become The Most Loved Programming Language over the past 8 years, according to the Stack Overflow Developer Survey from 2016 to 2023. I became curious about why Rust is so highly regarded. After learning and experimenting with the language, I realized that Rust deserves its reputation. Here are some of the reasons:

1. Excellent Error Handling

One of Rust's main advantages is its robust error handling system. Rust takes a different approach by utilizing the Result<T, E> data type to indicate possible failures in operations. By using Result, Rust enforces explicit handling of error cases, minimizing the likelihood of undetected or ignored errors.

2. Effective Null Value Handling

Rust adopts a different approach when it comes to handling null or invalid values. Instead, it encourages the use of Option<T>, which requires explicit handling of cases where a value may be empty. This helps avoid common mistakes associated with null values, such as accessing invalid memory.

I have written an article discussing how enums in Rust are leveraged effectively for error and null handling.

3. Performance

Rust is designed with a focus on high performance. Various benchmarks have shown that Rust performs on par with C/C++. By eliminating the overhead of features like garbage collection and heavy runtime environments, Rust produces efficient and fast code. Additionally, direct control over memory allocation and a strict type system further contribute to improved performance.

4. Safety

Ensuring safety is one of Rust's primary goals. Through its borrow checker and ownership system, Rust prevents common errors such as data races, null pointers, and memory leaks. By restricting rules on mutability and ownership transfer, Rust ensures that the programs you write are conceptually safe and have robust error handling.

5. Strong Typing

As someone coming from the TypeScript world, you'll find similarities between TypeScript and Rust's type systems. Both enforce static typing, support type annotations, generics, object-oriented programming concepts, and treat functions as first-class citizens. However, Rust's type system introduces unique features like its ownership model, borrowing rules, and pattern matching, which differentiate it from TypeScript.

With these features, Rust becomes a highly performant programming language while maintaining safety. However, it is considered challenging to learn and may require more time, especially when grasping the concepts of the Borrow Checker and Ownership. Understanding these foundational concepts is crucial to effectively use Rust. I have written an article titled "Understanding Rust Borrow and Ownership Concept" to assist you in comprehending these concepts more easily.
