This is supported on crate feature classes only.

The macro to simplify class definition.

struct TestClass;

impl TestClass {
    fn method(&self) {}
    fn static_func() {}
}

class_def! {
    TestClass
    // optional prototype initializer
    (proto) {
        proto.set("method", Func::from(Method(TestClass::method)))?;
    }
    // optional static initializer
    @(ctor) {
        ctor.set("static_func", Func::from(TestClass::static_func))?;
    }
    // optional internal refs marker (for gc)
    ~(_self, _marker) {
        // mark internal refs if exists
    }
}
