+ * applying a monitor update to a monitor. If full `ChannelMonitors` are
+ * persisted, then there is no need to persist individual updates.
+ *
+ * Note that there could be a performance tradeoff between persisting complete
+ * channel monitors on every update vs. persisting only updates and applying
+ * them in batches. The size of each monitor grows `O(number of state updates)`
+ * whereas updates are small and `O(1)`.
+ *
+ * See [`ChannelMonitor::serialize_for_disk`] for writing out a `ChannelMonitor`,
+ * [`ChannelMonitorUpdate::write`] for writing out an update, and
+ * [`ChannelMonitorUpdateErr`] for requirements when returning errors.
