Struct Timestamp 

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

8-byte-aligned u64 newtype that serializes as a string for JSON safety.

Implementations

impl Timestamp

pub const fn new(v: u64) -> Self

Wraps a raw u64.

pub const fn as_u64(self) -> u64

Returns the underlying u64.

impl Timestamp

pub fn now() -> Self

Current wall-clock time. May move backward if the system clock is adjusted.

pub fn is_zero(&self) -> bool

Returns true if the timestamp is zero.

pub fn now_non_decreasing() -> Self

Current time, clamped to never read earlier than a previous call. Repeated values are allowed.

pub fn now_increasing() -> Self

Current time, clamped to always read at least 1us later than a previous call. Never repeats a value.

pub fn later(self, rhs: TimestampDuration) -> Self

Timestamp shifted later by a duration, saturating at the maximum value.

pub fn earlier(self, rhs: TimestampDuration) -> Self

Timestamp shifted earlier by a duration, saturating at zero.

pub fn duration_since(self, older: Self) -> TimestampDuration

Duration from older to this timestamp, saturating to zero if older is later.
