Struct StaticComObject

pub struct StaticComObject<T>
where
    T: ComObjectInner,
{ /* private fields */ }

Enables applications to define COM objects using static storage. This is useful for factory objects, stateless objects, or objects which use need to contain or use mutable global state.

COM objects that are defined using StaticComObject have their storage placed directly in static storage; they are not stored in the heap.

COM objects defined using StaticComObject do have a reference count and this reference count is adjusted when owned COM interface references (e.g. IFoo and IUnknown) are created for the object. The reference count is initialized to 1.

Example

#[implement(IFoo)]
struct MyApp {
    // ...
}

static MY_STATIC_APP: StaticComObject<MyApp> = MyApp { ... }.into_static();

fn get_my_static_ifoo() -> IFoo {
    MY_STATIC_APP.to_interface()
}
