Snapshot
class Snapshot<out S : Any> @InternalWowApi constructor(val ref: AggregateRef, val version: Int, val scope: Scope, val access: Map<String, Any?>, val deleted: Boolean, val operator: Operator?, val firstEventTime: Long, val lastEventTime: Long, val state: S, val firstOperator: Operator? = null, val schedules: Map<String, ScheduleRule> = emptyMap())
An aggregate's latest committed state as a snapshot query and a state read answer it: the aggregate ref at version, its scope (owner and space), its access attributes (@Access, by name: a single one's value or null, a multiple one's values as a list), whether it is deleted, the operator of its last commit and the firstOperator of its first, the one that created it (each null for an anonymous caller), the times of its first and last events (epoch milliseconds), the schedules it keeps, each rule by its key, and its state, masked as the schema says.
Fields may be added: construct one with of; the constructor is internal to Wow.
