Well done!
We’ve journeyed through Rust’s essential composite data types, learning how to structure data beyond simple primitives. We started with structs, understanding how to define custom types with named fields, create instances, access and modify data, and add behavior using methods and associated functions within impl blocks. We also touched upon variations such as concise tuple structs and field-less unit-like structs.
Next, we explored enums, discovering how they allow us to define a type that can be one of several distinct variants. Crucially, we saw how these variants can hold associated data, making enums incredibly powerful for modeling different states, choices, or message types, often paired elegantly with Rust’s exhaustive match expression for safe handling. Finally, we looked at tuples as a simple, lightweight way to group a fixed number of values together, which is particularly useful for returning multiple values from functions...
