Rust supports two types of comments: normal inline (//) or multi-line (/* … */) for explaining your code, and special documentation comments that generate public-facing docs. Writing clear comments is key to keeping your Rust code readable and maintainable. One thing I learned early in Rust is that clear code is not always self-explanatory. Like […]

Rust has one of the most helpful compilers in any language. Its error messages are clear, actionable, and designed to teach. Still, as a beginner, compiler errors can feel overwhelming. Learning how to read and fix them is an essential Rust skill. One of the first things I noticed about Rust was how friendly and

Crates are Rust’s way of sharing reusable packages. You can use external crates to add functionality like random number generation, regex matching, or HTTP requests. Cargo makes it easy to include them in your project by adding them to your Cargo.toml file. When building something in Rust, you do not have to write everything from

Cargo is Rust’s official package manager and build tool. It handles everything from compiling your code, managing dependencies, running tests, and creating distributable packages. You use Cargo to create new projects and run them easily with simple commands. When I first started learning Rust, one of the best surprises was how smooth the experience was

Modules in Rust help you organize code by grouping related functions, types, and constants together. You define modules using the mod keyword and use them to break large files into smaller, manageable pieces. As your Rust project grows, putting everything in one file becomes messy. That is where modules come in. They allow you to

Rust treats most errors as recoverable using the Result type. But for serious, unrecoverable failures like bugs in logic or unsafe conditions, you use the panic! macro. It immediately stops the program and prints a message. Rust is designed to help you write safe, reliable code. Most of the time, it encourages handling errors through

Rust handles recoverable errors using the Result type, which represents either Ok(T) for success or Err(E) for failure. This pattern forces you to handle errors explicitly, avoiding silent failures or panics. Instead of crashing your program or hiding errors, Rust makes you deal with them. This is not just for safety, but also makes your

Rust does not have null values. Instead, it uses the Option type to represent values that may or may not exist. Option is an enum with two variants: Some(T) for a value, and None for the absence of a value. Null values cause many runtime bugs in other languages. Rust solves this by replacing null

Pattern matching with enums lets you destructure each variant and safely handle every possibility. Using the match expression, Rust forces you to deal with all cases, which helps prevent logic errors and unexpected behavior. In Rust, pattern matching is how you interact with enums effectively. It gives you fine control over what each variant means

An enum in Rust is a type that can represent one of several possible variants, each optionally holding different types of data. Enums are ideal for modeling choices, states, or patterns like Option, Result, and more. If structs in Rust let you group fields together, enums let you define a type that can be only
