updateErased
fun updateErased(previous: ModifierElement, current: ModifierElement, node: ModifierNode): DirtyMask(source)
Updates one retained modifier node through its typed diff hook.
The runtime invokes this function on the owning tree thread. The returned mask contains only phases affected by the property change. A failure propagates without a last-good fallback and poisons the owning tree.
Return
the phases affected by the update.
Parameters
previous
the retained description.
current
the incoming description.
node
the retained node to update.
Throws
when a description or node violates this token.
when the update hook fails.
