Macro oop_inheritance::class

class!() { /* proc-macro */ }

Defines a class.

Syntax

use oop_inheritance::Node;

class! {
    struct MyClass: SuperClass1 < SuperClassN < Node {
        // fn x() -> f64
        // fn set_x(x: f64) -> Self
        x: f64 = 0.0,
        // fn y() -> Arc<f64>
        // fn set_y(y: Arc<f64>) -> Self
        ref y: f64 = 0.0,
    }
    // fn new() -> Self
    fn constructor() {
        super();
    }
}

Topmost super class

The topmost super class of a class defined by class! must be oop_inheritance::Node; otherwise it is undefined behavior.

Reference parameter

If it is desired to receive a parameter as a specific class or any subclass, take a parameter implementing AsRef<C>:

fn my_function(object: impl AsRef<MyClass>) {
    let object = object.as_ref();
    // object: &MyClass
}
