I dislike all these 'expressive' or how abstract rust as a language can be from what it's trying to achieve which is to be a 'systems programming language' on par with c (c++ is not the same as c). Show the resulting assembly for both a C version and a Rust version, now map both the rust version and c version to the resulting assembly.
Rust is meant to replace C++, not C. The original motivation was that the Mozilla devs were sick and tired of all the subtle ways bugs can sneak into a large, complex C++ code base.
The ultimate aim is to write the nextgen browser engine not an operating system kernel or some embedded code for a system with 4kB RAM.
