Rust traits are not binary-compatible with C++ vtables, so no, you cannot use them directly.
I think it's possible to implement COM interop by doing some clever code generation via macros. I briefly looked into doing this a couple of months ago, but at the time it was not possible to specify calling convention on function pointers, and you can't generate COM vtables without that. Once v0.7 is out, I'll try again.
