//! This file handles the supporting infrastructure for the `Component` trait and `Properties` which makes it possible
//! for components to be used within Nodes.
//!

/// The `Component` trait refers to any struct or funciton that can be used as a component
/// We automatically implement Component for FC<T>
// pub trait Component {
//     type Props: Properties<'static>;
//     fn builder(&'static self) -> Self::Props;
// }

// // Auto implement component for a FC
// // Calling the FC is the same as "rendering" it
// impl<P: Properties<'static>> Component for FC<P> {
//     type Props = P;

//     fn builder(&self) -> Self::Props {
//         todo!()
//     }
// }

/// The `Properties` trait defines any struct that can be constructed using a combination of default / optional fields.
/// Components take a "properties" object
// pub trait Properties<'a>
// where
//     Self: Debug,
// {
//     fn call(&self, ptr: *const ()) {}
// }

// // Auto implement for no-prop components
// impl<'a> Properties<'a> for () {
//     fn call(&self, ptr: *const ()) {}
// }
