I have no opinion regarding rust suitability as a game language, but your answer doesn't sound right.

The actual reason is much simpler. The industry is built on a handful of game engines. Those engines are extended or scripted in C++ or C#. Thus the vast, vast majority of the work force will only have experience with those languages and the entirety of game studios' tooling is built around those. The end.
