But Rust is a system level programming language, it was designed 
for writing device drivers, filesystems, and other resource 
constrained and latency critical software, where languages with 
runtime environments can't be used, even if you're okay with them

Even the actual software libraries used by higher level languages 
in mobile applications are wrappers over the extremely 
power/compute efficient C/C++ libraries that were written with 
misery and paranoia, it's not as if a higher level languages' 
tech stack doesn't involve lower level language, but the opposite 
is true

Thus, Rust always assumes the worst case scenarios and makes the 
programmer distort their code to make it compile, and, unless you 
use lots of unsafe, the code really belongs to "if it compiles, 
it doesn't have memory bugs" camp of software
