Defining and Instantiating Structs

Structs allow you to create custom data types by grouping related values together. Each field has a name and a type.

snippet.rs

rust

struct User {
    username: String,
    email: String,
    active: bool,
}
 
fn main() {
    let user1 = User {
        email: String::from("[email protected]"),
        username: String::from("someuser123"),
        active: true,
    };
}

Breakdown

struct User { ... }

Defines the structure of the custom type with field names and types.

let user1 = User { ... }

Creates an instance by assigning values to all defined fields.
