> That's why you don't let widgets hold program state, they should just propagate deltas and display current state. It's a different way of thinking about how UI can work, but imho it has a lot of benefits aside from just speed and safety.

My (limited) understanding is that you're describing an immediate mode GUI (as opposed to a retained GUI) and that one isn't strictly better than the other, but rather there are tradeoffs. In either case, I would be a little perturbed if implementing/using a retained mode GUI in Rust was prohibitively difficult even if immediate mode were strictly superior (the language probably shouldn't force such choices). Of course, I'm opining beyond my expertise, so I'm happy to be corrected.

I'm definitely no GUI framework expert, but I didn't necessarily mean to imply an immediate mode architecture. Personally I've been writing a lot of code that way in retained mode frameworks. There's some duplication of data but it's not a huge deal when a widget's state is just single variant, which covers just about all I need.
