Reviewing commits for a security-critical project written in C or C++ can be incredibly tedious. I've spent an entire day trying to validate that the assumptions made by a 10-line change are memory-safe in the context of the larger program. These reviews are incredibly mentally draining, and even when I'm done I'm not 100% sure that I didn't miss something and let a vulnerability into the codebase.

Rust is a breath of fresh air in comparison. Worrying about memory safety isn't even a concern for the vast majority of commits that don't touch modules with unsafe code. All assumptions made about the lifetimes of references are made explicit in the code, and checked by the compiler. On rust projects I find I have much more mental energy to use against other aspects of the problem.
