Trait ComponentFunction

pub trait ComponentFunction<Props, Marker = ()>: Clone + 'static {
    // Required method
    fn rebuild(&self, props: Props) -> Element;

    // Provided method
    fn id(&self) -> TypeId { ... }
}

Any component that implements the ComponentFn trait can be used as a component.

This trait is automatically implemented for functions that are in one of the following forms:

• fn() -> Element
• fn(props: Properties) -> Element

You can derive it automatically for any function with arguments that implement PartialEq with the #[component] attribute:

#[component]
fn MyComponent(a: u32, b: u32) -> Element {
    rsx! { "a: {a}, b: {b}" }
}

Required Methods

fn rebuild(&self, props: Props) -> Element

Convert the component to a function that takes props and returns an element.

Provided Methods

fn id(&self) -> TypeId

Get the type id of the component.

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.
