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 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…

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…

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…

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…

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.…
