they use https://github.com/meetecho/janus-gateway as the webrtc backend, at least according to https://opentalk.eu/en/open-source-code-und-community. so the rust part is probably just for chat and signaling.
Zoom and Gmeet are usable (usually calls are stable and quality is ok) but closed-source shit, and I had a lot of stability issues on public jitsi instances (though I never self-hosted).
I've tried opentalk for the first time a few weeks ago (it's included in my email provider plan) and it worked fine.

What's wrong with jitsi tho?
It did, didn't it? It became so popular that meet.jit.si had to shutdown. Fortunately theres tons of free ones run by other orgs.
