Struct alchemy_lifecycle::rsx::VirtualNode

pub struct VirtualNode {
    pub tag: &'static str,
    pub styles: StylesList,
    pub create_component_fn: fn(key: ComponentKey) -> Box<dyn Component>,
    pub props: Box<dyn Any>,
    pub children: Vec<RSX>,
}

A VirtualNode is akin to an Element in React terms. Here, we provide a way for lazy Component instantiation, properties, children and so on.

Fields

tag: &'static str

Used in debugging/printing/etc.

styles: StylesList

Used for determining which CSS styles should be applied to this node. This property is accessed often enough that it's separated out here.

create_component_fn: fn(key: ComponentKey) -> Box<dyn Component>

Component instances are created on-demand, if the reconciler deems it be so. This is a closure that should return an instance of the correct type.

props: Box<dyn Any>

When some RSX is returned, we scoop up the props inside a special block, and then shove them in here as an Any object. When you derive(Props) on a Component struct, it creates a setter that specifically handles downcasting and persisting props for you.

children: Vec<RSX>

Child components for this node.
