Struct ComObject 

pub struct ComObject<T> { /* private fields */ }

One interface of a Rust-implemented COM object as native code sees it (a “COM callable wrapper” of the MicroCom runtime): the first word is the vtable pointer, so a *mut ComObject<T> is the interface pointer; the second leads to the object the wrapper belongs to.

An object has one wrapper per interface it was made with, as the shadow of an object has in the MicroCom runtime. They share the reference count and the value, and QueryInterface on any of them answers with the wrapper of the interface asked for.

Implementations

impl<T> ComObject<T>

pub unsafe fn value<'a>(this: *mut c_void) -> &'a T

Recovers the Rust value from the this pointer a thunk receives: the pointer of any interface of the object.

Safety

this must point at a live ComObject<T>.

pub unsafe fn ref_count(this: *mut c_void) -> u32

Current reference count (diagnostics/tests only).

Safety

this must point at a live ComObject<T>.
