class roboto.domain.platform_events.once_per.OncePer

Bases: roboto.compat.StrEnum

A grain an event offers for deduplication: the occurrence itself, or an entity the event names.

This is an event’s vocabulary, not a trigger’s. Each PlatformEventType declares the grains it supports, and how an occurrence projects onto each, in its PlatformEventDescriptor; that projection is what turns one occurrence into one idempotency token. A trigger only chooses among the grains its events offer, and its choice must be legal for every event type it subscribes to.
