Would you build Rust GUIs like this?

Hey folks! For a while, I've been working on this project for Rust GUIs called Pax. I recently decided to "launch early" and start developing it in the open.

Pax extends Rust with a syntax for declarative component-based GUIs. Pax is in alpha preview.

Would you use an approach like the following for building GUIs in Rust? What do you like/dislike about it? What questions would you have about it? What tough use-case might you have for it? How clear are the messaging & documentation? Any thoughts, friendly and critical, are welcome.

//increment-me.rs

use pax::*;
use pax_std::{Text};
use pax_std::forms::{Button, ArgsButtonSubmit};
use pax_std::layout::{Stacker};

#[pax(
  <Stacker cells=2>
    <Text>{"I have been clicked " + self.num_clicks + " times."}</Text>
    <Button @submit=self.increment>"Increment me!"</Button>
  </Stacker>
)] 
pub struct IncrementMe {
  pub num_clicks: Property<i64>
}
impl IncrementMe {
  pub async fn increment(mut self, args: ArgsButtonSubmit) {
    let old_num_clicks = self.num_clicks.get();
    self.num_clicks.set(old_num_clicks + 1);
  }
}

The above defines a UI component, IncrementMe, which may then be used elsewhere via use crate::IncrementMe; in Rust and <IncrementMe /> in a Pax template

Much of the above functionality is already built or underway -- see:

• The project on GitHub
• The website
• The docs
• A running example

p.s. seeking collaborators! EDIT: re-formatted code example to be friendlier to old.reddit.com
