Explanation, details:

I'm trying to create a simple web-page app using examples while I review the documentation. However, I encounter an error displayed on the terminal when I attempt to execute it with trunk serve --open.

Sorry if, in the end, the issue isn't actually a problem and it turns out my code is incorrect. My fault.

My code:

Cargo.toml

# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html
[dependencies]
yew = { version = "0.21", features = ["csr"] }
stylist = { version = "0.13.0", features = ["yew", "parser"] }

App.rs

use yew::prelude::*;

#[function_component(App)]
pub fn app() -> Html {
    let a: Style = style!(r#"background-color: red;"#).unwrap();
    html! {
        <main>
            <div class={a}>
                {"da"}
            </div>
        </main>
    }
}

Main.rs

mod app;

use app::App;

fn main() {
    yew::Renderer::<App>::new().render();
}

[Rustc version] rustc 1.76.0 (07dca489a 2024-02-04)

[Cargo version] cargo 1.76.0 (c84b36747 2024-01-18)

[Trunk version] trunk 0.18.8

The docs I read: link = https://docs.rs/stylist/latest/stylist/

This is the entire message from the terminal.
