Struct TimerRegistrationId 

pub struct TimerRegistrationId { /* private fields */ }

Inert identity of one registration and its cumulative measurements.

Equality proves a shared counter lifetime only within one canister’s observed runtime history. Reinstalls or restored/forked canister state are separate histories. The sequence never wraps: exhaustion rejects registration. Values are not provider handles or mutation capabilities.

Implementations

impl TimerRegistrationId

pub const fn epoch(self) -> TimerEpoch

Return the runtime reset boundary containing this registration.

pub const fn sequence(self) -> u64

Return the nonzero registration sequence within this runtime epoch.
