No thanks, I’ll be staying with
datastruct.nextState()rather thanconst nextState = prevState.nextState()
You can easily do the first option in Rust, you just use the mut keyword. That's it, nothing more than that. And you'll find that you quite rarely have to do that, and when you do it, it's actually quite a useful signal to be aware of, since mutability sometimes means a bit more surprising data changes.
Sorry but this is just false. URIs can easily encode UTF-8 characters and it's perfectly standard to do so via percent-encoding. Example: https://en.wikipedia.org/wiki/😂. Your browser will even automatically convert that 😂 into the appropriate percent-encoding and will even display the emoji in the address bar, even if that is not the "true" URI.
This is, if you ask me, an unnecessary limitation in Lemmy.
