Struct EventPublicationKey 

pub struct EventPublicationKey(/* private fields */);

Stable deterministic identity for one logical transition’s event publication.

Implementations

impl EventPublicationKey

pub fn derive( transition_identity: &str, ordinal: u32, scope: &DurableHostEventScope, event_class: DurableHostEventClass, ) -> SessionStoreResult<Self>

Derive an unambiguous publication key from a transition identity and event ordinal.

The transition identity must itself be stable across retries, for example a durable mutation receipt, admission identity, or sealed run-evidence identity.

Errors

Returns an error when transition_identity is empty.

pub fn as_str(&self) -> &str

Return the publication-key string.
