I would have argued Rust isn't the right choice for a web framework unless the team is rust-first because the memory guarantees aren't really needed, and you're better off with occasional GC pauses and faster development velocity.
This is perhaps a bit off topic, but I don't think rust is a one-trick-pony IRT memory safety. I hear this a lot, mainly from Rust programmers. [surprisingly]
That’s my take as well. To each their own, but for me there are other, GC-ed, languages that are performant enough and way more productive (and I love Rust!)
