This is a WIP module
|
|
|
|
Subtrees allow the virtualdom to split up the mutation stream into smaller chunks which can be directed to different parts of the dom.
|
|
It's core to implementing multiwindow desktop support, portals, and alternative inline renderers like react-three-fiber.
|
|
|
|
The primary idea is to give each renderer a linear element tree managed by Dioxus to maximize performance and minimize memory usage.
|
|
This can't be done if two renderers need to share the same native tree.
|
|
With subtrees, we have an entirely different slab of elements
