Struct Metadata 

pub struct Metadata<T: MetadataKey> {
    pub content: AnyView,
    pub value: T,
}

Represents a view that carries additional metadata of type T.

This struct allows attaching arbitrary data to a view component. The metadata is expected to be handled by a renderer, and will panic if not properly caught.

Metadata is transparent for layout system, it is not a native view.

Fields

content: AnyView

value: T

The metadata value associated with the content.
