Halogen.VDom.Types

data VDom a w

The core virtual-dom tree type, where a is the type of attributes, and w is the type of "widgets". Widgets are machines that have complete control over the lifecycle of some DOM.Node.

The Grafted constructor and associated machinery enables bimap fusion using a Coyoneda-like encoding.
