> less time debugging

I would say it isn't even the debugging. As many of the C++ programmers here have said as you get good at C++ this becomes something that you are vigilant for and it rarely actually gets written. But just the lack of even needing to think about it is a huge load off my mind. When I used to write C++ I never really realized how vigilant I was. Every time I added code into the middle of a function I had to double check all of the lifetimes, every time I shorted the lifetime of a variable I had to search for it to the end of the function. Just not having to worry about this much really frees your mind for thinking about other things.

And what are you thinking about now?

For me it was what lifetimes and types to use to make my program work. Just as it was in C++, but with a static verification step at the end which most of the time got in my way.

Rust makes lots of sense in high-churn projects or projects which have very high security requirements (like browsers). Otherwise I’d think carefully about using it.

You had to think about lifetimes in C++, too, but in Rust at least they're written down and enforced.
