Rust Programming Basics
1. If Else
An essential guide to Mastering Conditional Logic: Basic `if/else` Statements in Rust - Learn how `if/else` statements form the core of decision-making and program flow in Rust. Discover their power as expressions for concise value assignments, focusing on type consistency and Rust's key syntax rules. Duration: 2min
2. If Else Exercises
A hands-on introduction to If and else statement - Learn to make decisions and control execution paths in Rust using `if` and `else` statements. Solidify your understanding by implementing functions to find the minimum, maximum, and sign of numbers. Reading Time: 0min
3. Loop
An in-depth guide to Rust's Looping Constructs - Command `loop`, `while`, and `for` to orchestrate code repetition, and navigate ranges, arrays, and vectors effectively. Master vector iteration with `into_iter()` (ownership) vs. `iter()` (borrowing), and leverage `loop` expressions to return computed values. Duration: 6min
4. Loop Exercises
A foundational exploration of Loop - Build core programming skills by tackling exercises on finding minimums, maximums, and determining the sign of integers. You'll use conditional logic to implement these fundamental operations, preparing you for more complex iterative algorithms. Reading Time: 0min
5. Match
An essential introduction to Mastering Rust's `match` Control Flow - Discover the power of Rust's `match` expression, a tool for pattern matching that guarantees every case is handled. Learn to use `match` with ranges, enums like `Option` and `Result`, and as an expression that returns a value. Duration: 6min
6. Match Exercises
An illuminating look at Pattern Match - Discover how Rust's `match` expressions provide elegant and powerful ways to control program flow based on patterns. You'll solidify your understanding by implementing number-to-string conversions and custom logic for `Option` types. Reading Time: 0min
7. If Let
A concise look at Rust's `if let` for specific pattern matching - Explore how `if let` simplifies your code when you only need to handle one variant of an enum like `Option` or `Result`. This approach avoids the boilerplate of a full `match` statement, leading to cleaner and more direct conditional logic. Duration: 1min
8. If Let Exercises
A targeted guide to using `if let` for `Option` Handling - Learn to effectively use Rust's `if let` statement to conditionally extract values from `Option` types. You'll implement a function that returns the contained value of a `Some` or a specified default for `None`. Reading Time: 0min
