Note that what Rust calls the "C" ABI isn't actually the C ABI; rather it's a sane interpretation of the psABI for your platform in terms of Rust constructs, chosen so that where there's multiple choices, the chosen option maps to what most C compilers for that platform will choose. It's just that if you called it the psABI, people would get confused (most of us don't look into this level of detail), whereas calling it the "C ABI" helps people's intuition, even though it's as accurate as calling Linux a Solaris-alike.
