Attribute Macro component 

#[component]

Component attribute macro for defining reusable components

Transforms a function into a component with automatic prop handling. The first parameter must be cx: &Arc<Context>. Remaining parameters become component props.

Example

#[component]
pub fn Counter(cx: &Arc<Context>, initial: &i32) -> View {
    let count = use_state(*initial);
     
    Arc::new(move |ctx| {
        ctx.draw_text(Point { x: 0, y: 0 }, &format!("Count: {}", count.get_dl()));
    })
}
