Structs

Types are PascalCase. Structs can be named tuples:

#![allow(unused)]
fn main() {
#[derive(Debug)]
struct Rgb(u8, u8, u8);

let colour = Rgb(5,5,5);
println!("{:?}", colour);
}

or with named fields

#[derive(Debug)]
struct Person {
    name: String,
    age: u8,
}

fn main() {
    let age = 38;
    let me = Person {
        name: "Liam".to_string(),
        age
    };
    println!("{:?}", me);
}

Struct update

#![allow(unused)]
fn main() {
let user2 = User {
    email: String::from("another@example.com"),
    ..user1
};
}
