Struct Timestamp 

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

A point on a monotonic timeline, in nanoseconds since an origin the caller chooses. Only differences between timestamps mean anything; the origin itself never enters the schedule.

Absolute timestamps rather than per-frame deltas, on purpose. One subtraction happens in one place (every caller computing its own can compute it wrongly), a clock that went the wrong way becomes Nanos::ZERO instead of 1.1 trillion phantom steps, the first-frame branch disappears into the constructor’s start argument, and resynchronizing after a known pause is trivially correct.

Implementations

impl Timestamp

pub const fn from_nanos(nanos: u64) -> Self

pub const fn get(self) -> u64

The raw offset from the caller’s own origin. Meaningful only to whoever chose that origin — for logging and for building a synthetic timeline, never for arithmetic against another clock.

pub const fn saturating_since(self, earlier: Self) -> Nanos

The span from earlier to self, or Nanos::ZERO if self is the earlier of the two. A backwards clock is a defined, harmless input rather than a wrapped u64.

pub const fn saturating_add(self, span: Nanos) -> Self

self + span, saturating at the end of the representable timeline (~584 years).
