Trait freya::prelude::ComponentFunction

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

    // 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) -> Result<VNode, RenderError>

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.

Object Safety

This trait is not object safe.
