structs - Rust By Example
Description: A description

# structs

Similarly, a `struct` can be destructured as shown:

    fn main() {
        struct Foo {
            x: (u32, u32),
            y: u32,
        }

        // Try changing the values in the struct to see what happens
        let foo = Foo { x: (1, 2), y: 3 };

        match foo {
            Foo { x: (1, b), y } => println!("First of x is 1, b = {},  y = {} ", b, y),

            // you can destructure structs and rename the variables,
            // the order is not important
            Foo { y: 2, x: i } => println!("y is 2, i = {:?}", i),

            // and you can also ignore some variables:
            Foo { y, .. } => println!("y = {}, we don't care about x", y),
            // this will give an error: pattern does not mention field `x`
            //Foo { y } => println!("y = {}", y),
        }
    }
