For Loops
For loops are a fundamental construct in Rust programming, allowing developers to iterate over collections and execute code for each item efficiently. In this guide, we'll dive deep into mastering for loops in Rust, exploring various scenarios and best practices. Basics of For Loops At its core, a for loop in Rust iterates over each item in a collection, such as an array, and executes a block of code for each item. Let's consider a simple example: let message = ['h', 'e', 'l', 'l', 'o']; for item in message { println!("{}", item); } or let message = ['h', 'e', 'l', 'l', 'o']; for item in message.iter() { println!("{}", item); } In this example, the for loop iterates over the elements of the message array, printing each character individually. Rust's for loop automatically handles the iteration process, making it easy to work with collections. Enumerating Items Som...
