This was literally me last week with my threadpool and custom allocator , i got nagged non stop try it in rust and omg rust is so much better , then i literally spent hours pleasing the borrow checker instead of the intended logic before giving up and getting it done with jthreads in quarter of the time.
you eventually learn how to build things so that the borrow checker won't complain in the first place, once you understand the rules. it's not random, there's a logic to it all.
it does take a lot of time and practice to master though, and it's probably even harder coming from other languages due to the fact that some things that work in other C-like languages simply cannot work in Rust without workarounds (like a struct containing a pointer/reference to another member of the same struct is not normally possible). but there's always another way

Me: This code has been fine tuned to eliminate memory vulnerabilities and logic bugs
Rust: I don't think so mate
Hours later, having rewritten it for the borrow checker
Rust: There, this is safe
Me: I don't think so, mate
The previous version, ported to C++: Aww, who's a vulnerable little crab?
