Class OngoingAvailability

source code

Information about ongoing availability in a node

An OngoingAvailability object contains information not just about the availability starting at a given time, but also how that availability diminishes over time. Thus, it the object to use when determining if, starting at a given time, it is possible to fit some capacity up to a certain time (with or without preempting other leases).

Typically, you will want to create an OngoingAvailability object using the get_ongoing_availability method in AvailabilityWindow
