rustHow to get struct fields in Rust

Structs in Rust are used to store data in a structured way. To access the fields of a struct, you can use the dot notation. For example:

struct Point {
    x: i32,
    y: i32,
}

let point = Point { x: 0, y: 0 };

println!("The x coordinate is {}", point.x);

Output example

The x coordinate is 0

The code above creates a struct called Point with two fields, x and y. Then, it creates an instance of the Point struct and prints out the value of the x field.

You can also use the let keyword to destructure a struct and assign its fields to variables. For example:

let Point { x, y } = point;

println!("The x coordinate is {}", x);

Output example

The x coordinate is 0

In the code above, the let keyword is used to destructure the point struct and assign its fields to the x and y variables. Then, the value of the x variable is printed out.
