not a unit struct, unit variant or constant enum match

Comment

unit enum

enum A { One }
match something {
    A::One => { /* Do something */ }
}

tuple enum

enum B { Two(u8, bool) }
match something {
    B::Two(x, y) => { /* Do something */ }
}

struct enum

enum C { Three { a: f64, b: String } }
match something {
    C::Three { a: another_name, b } => { /* Do something */ }
}

pattern matching

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

let point = Point { x: false, y: true };

match point {
    point.x => println!("x is true"),
    point.y => println!("y is true"),
}
match point {
    Point { x: true, .. } => println!("x is true"),
    Point { y: true, .. } => println!("y is true"),
    _ => println!("something else"),
}
