If it is a "drop-in replacement" the rust compiler should be able to compile C code - it can't.
Rust is not a drop-in replacement for C, it’s a drop-in replacement for C++.
It's a drop-in replacement for neither since it's an entirely different language.
C++ went to some great pain to be a drop-in replacement for C; you can "drop in" a C++ compiler in your toolchain and still compile your C code (mostly).

This was kind of true till C99, but not so much anymore. restrict is the most obvious offender but far from the only one[1].

I think Rust will eat more and more of the stack.
It has similar performance as C/C++, but feels more higher level. It's a drop-in replacement for C and is developed by a company that devs like.
