Trait Component 

pub trait Component: ComponentKey + 'static {
    // Required method
    fn render(&self) -> impl IntoElement;

    // Provided method
    fn render_key(&self) -> DiffKey { ... }
}

Encapsulate reusable pieces of UI by using the Component trait. Every Component creates a new layer of state in the app, meaning that implementors of Component can make use of hooks in their Component::render method.

#[derive(PartialEq)]
struct ReusableCounter {
    pub init_number: u8,
}

impl Component for ReusableCounter {
    fn render(&self) -> impl IntoElement {
        let mut number = use_state(|| self.init_number);
        label()
            .on_press(move |_| {
                *number.write() += 1;
            })
            .text(number.read().to_string())
    }
}

Required Methods

fn render(&self) -> impl IntoElement

Provided Methods

fn render_key(&self) -> DiffKey

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
