Course 19 - Ultimate Rust Crash Course | Episode 2: Rust Core Foundations: Data Types, Control Flow, and String Handling

In this lesson, you’ll learn about:Core Data Representations in Rust:Scalar types: integers (signed i and unsigned u), floating-point types (f32, f64), booleans, and Unicode char values.Compound types: tuples (accessed via indexing or destructuring) and fixed-size arrays stored on the stack, along with their practical limits.Project Organization and Reusability:Moving logic into a library file (lib.rs).Exposing functions with the pub keyword and importing them using use statements.Control Flow and Program Logic:Using if as an expression that returns a value, replacing traditional ternary operators.Working with loops: loop (including labeled breaks), while, and for.Iterating with ranges, both exclusive (0..50) and inclusive (0..=50).Understanding Rust Strings:Differences between borrowed string slices (&str) and owned, heap-allocated String types.Why UTF-8 encoding prevents direct character indexing.Safely accessing string data using iterators like .bytes(), .chars(), and .nth().Practical Application:Processing command-line arguments as vectors of strings.Applying loops and conditional logic to perform numeric operations such as summing ranges or repeatedly modifying values until a condition is met.You can listen and download our episodes for free on more than 10 different platforms:https://linktr.ee/cybercode_academy
