But Rust doesn't have C++ interop at all?

It also doesn't have the disadvantages of Swift. Once the promise of Swift/C++ interop is gone there isn't enough left to recommend it.
Yeah, that part doesn't make much sense to me. IMO, Swift has reasonably good C++ interop[1] and Swift's C interop has also significantly improved[2] since Swift 6.2.

It may have in the future. Crubit is one effort in this direction: https://crubit.rs/
There is also cxx.rs, which is quite nice, albeit you have to struggle sending `std` types back and forth a bit
Rust has cxx which I would argue is "good enough" for most use cases. At least all C++ use cases I have. Not perfect, but pretty damn reasonable.
It's technically Rust -> C -> C++ as it stands right now
You can do it via the C ABI, and use opaque pointers to represent higher-level Rust/C++ concepts if you want to.
Firefox is a mixed C++ / Rust codebase with a relatively close coupling between Rust and C++ components in places (layout/dom/script are in C++ while style is in Rust, and a mix of WebRender (Rust) and Skia (C++) are used for rendering with C++ glue code)
