Rust's Option Type: Handling Null Values With Grace
Rust's Option enum: a flexible way to represent null values. It can contain something (Some) or nothing (None), making it perfect for handling optional data and errors.
I'm a self-taught developer, focusing on the Rust language.

Creating middleware in Actix Web involves defining a struct implementing the `Middleware` trait with `forward` & `init` methods. Middleware can be used to wrap services, e.g., checking API keys in request headers.
Exploring Rust's single-value data types: integers (i32), floating-point numbers (f64), booleans, and characters. Learn how to declare variables and perform basic math operations in this beginner-friendly guide.
Learning Rust: Comments, Variables, Mutability & Shadowing. Comments are crucial for understanding code, variables are immutable by default, but can be made mutable with `mut`. Shadowing allows transforming values without changing their type.
Rust constants declared with `const` keyword, immutable by default, avoiding "magic values" for more maintainable code.
Vectors in Rust are a collection that can grow/shrink in size, storing items next to each other in heap memory. Created with `Vec::new()` or initialized with values, elements accessed/modified using indexing or `.get()`.
Learned to code with Rust in 2020, now mastering its power & performance. Steep learning curve but worth it! Get started with Rust & Visual Studio Code using Cargo package management tool. Say hello to coding in Rust!
Mastering crates, packages & modules in Rust takes time & practice. Understand crate types (binary & library), package structure, modules for organization & privacy control, paths, use keyword & namespace operator to write maintainable code.
Finished Chapter 2 of "The Rust Book" & recreated the Guessing Game from memory with some overengineering. Highlights important concepts in Rust & serves as a great jumping off point for exploration. GitHub link at end of article.
Rust's match construct controls program flow like if-else, but more powerful & addictive! Evaluate multiple possibilities, handle all types with exhaustive matches, and catch common outcomes with the `_` pattern.
Rust structs: field init shorthand, update syntax, tuple & unit structs explored. Learn how to initialize and update structs with ease, and discover the power of tuple and unit structs.
Learn how to control flow with loops in Rust: loop, while, and for. Master repetition of code until desired outcome or event.
Rust's basic decision logic: `if`, `else if` & `match`. Control flow with conditional statements for different code paths & outcomes. Learn how to make decisions in your Rust programs!
Rust's compound data types: Tuples & Arrays explained. Learn how to create, access & use them in your code.
In Rust, constants are immutable values bound to a name, avoiding "magic values" and making code updates easier. Declare with `const` keyword, all caps convention, type annotation, and binding value with `=` operator.
