var customDelegateBindersForMountSpec: MutableMap<Class<*>, RenderUnit.DelegateBinder<Any, Any, Any>>?

Returns a nullable map of RenderUnit.DelegateBinder that is aimed to be used to set the optional mount binders right after creating a MountSpecLithoRenderUnit.

fun addCustomBinders(delegateBindersMap: Map<Class<*>, RenderUnit.DelegateBinder<Any, Any, Any>>? = null)

The goal of this method is to add the optional mount binders to the associated to this LithoNode. If we are dealing with a Primitive, we will get the corresponding LithoNode and associate the binders map as optional mount binders. For this reason, this method should be called as soon as their RenderUnit is created. In Litho, this happens in the Resolve phase, specifically when the mount content preparation is invoked.
