Game devs only change programming languages when console and OS vendors force them to do so.
That is how they moved from Assembly into C, C into C++, adopted Objective-C, adopted C# in their tools, accepted external middleware like Unreal or Unity.
So until one of the big desktop or console owners releases an SDK where Rust is the language, they will hardly adopt it.
Sure a few indies might do it, but it will be a blip on the radar of the usual Game Developer Conference attendees.
