Struct TimerId 

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

Handle to a durable timer that wakes at a persisted instant, surviving process restarts.

Examples

use zeph_durable::TimerId;

let id = TimerId::new();
assert_ne!(id, TimerId::new());

Implementations

impl TimerId

pub fn new() -> Self

Mint a fresh timer identity.

pub fn derive(execution_id: ExecutionId, step_id: StepId) -> Self

Derive the deterministic timer id for a (execution_id, step_id) position.

As with PromiseId::derive, a resumed sleep_until at the same program point re-derives the same id and re-attaches to the journaled durable_timers row, so a timer that fired during downtime is recognized on replay rather than re-armed afresh (FR-DE-06).

Examples

use zeph_durable::{ExecutionId, StepId, TimerId};

let exec = ExecutionId::new();
assert_eq!(
    TimerId::derive(exec, StepId::new(1)),
    TimerId::derive(exec, StepId::new(1)),
);

pub fn as_uuid(self) -> Uuid

Return the underlying UUID.
