Trait Component

pub trait Component: 'static {
    type Builder;

    // Required methods
    fn render(&self, ctx: Context<'_>) -> View;
    fn updated(&self) -> bool;

    // Provided methods
    fn native_type(&self) -> Option<NativeType> { ... }
    fn location(&self) -> Option<(u32, u32)> { ... }
    fn key(&self) -> Option<&str> { ... }
}

The trait representing a component.

Users should not implement this trait manually but instead use the component attribute. However, native component implementations may need to use manual component implementations.
