For sure. I didn't mean to suggest that nobody from C land would enjoy Rust. Just that I think the trend will be that more C++ people move to Rust than C people.

But my point of view is quite biased. I am still baffled that people would start new projects in C instead of just using a strict subset of C++, at least: classes, only trivial templates for generics, references, maybe smart pointers depending on what you're doing, but no STL, no exceptions, no inheritance, etc.
