Function Stack

a public function. rust let o: Object<IMy> = ...; // calling a public function let i: u32 = o.B(); rust trait IMyEx { // a definition fn B(&self) -> u32; } impl IMyEx for Object<IMy> { // an implementation of the public function fn B(&self) -> u32 { // calling a virtual function. unsafe { (self.interface().B()(self) } } }
a virtual function. rust #[repr(C)] pub struct IMy { // a definiton of the virtual function pub B: unsafe extern "stdcall" fn(this: &Object<IMy>) -> u32 } trait IMyVmtFn: Class<Interface = IMy> where CObject<Self>: IMyEx { // an implementation of the virtual function extern "stdcall" fn B(this: &Object<IMy>) -> u32 { // calling a function implementation unsafe { Self::to_cobject(this) }.B() } }
a function implementation. rust trait IMyEx { // a definition fn B(&self) -> u32; } impl IMyEx for CObject<X> { // an implementation of the function. fn B(&self) -> u32 { self.value.0 } }
