Struct Timestamp 

pub struct Timestamp { /* private fields */ }

HLC timestamp — packs (wall_ms: 48, counter: 16) into a single u64. This is the canonical in-memory and on-wire representation of a LogEntry.timestamp value. Plain numeric comparison on the raw u64 preserves causal order (wall dominates, counter tie-breaks).

Implementations

impl Timestamp

pub fn from_parts(millis: u64, counter: u16) -> Self

Compose from (millis, counter) parts. millis must fit in the top 48 bits — Unix-epoch ms stays under 2^48 until roughly year 10895. A larger value would shift its high bits off the top of the u64 (<< discards them rather than panicking) and silently wrap the wall component back toward zero, shattering monotonicity — so we panic instead. Unreachable for any real timestamp.

pub fn from_raw(data: u64) -> Self

Reconstruct from the packed u64 representation.

pub fn raw(&self) -> u64

The packed u64 representation: (millis << 16) | counter.

pub fn millis(&self) -> u64

Wall-clock component: Unix epoch milliseconds. Top 48 bits.

pub fn counter(&self) -> u16

Monotonic counter within a given millisecond. Low 16 bits.

Trait Implementations

impl Clone for Timestamp

fn clone(&self) -> Timestamp

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Timestamp

impl Debug for Timestamp

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Timestamp

fn default() -> Timestamp

Returns the “default value” for a type.

impl Eq for Timestamp

impl From<Timestamp> for u64

fn from(ts: Timestamp) -> u64

Converts to this type from the input type.

impl From<u64> for Timestamp

fn from(data: u64) -> Self

Converts to this type from the input type.

impl Hash for Timestamp

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Timestamp

fn cmp(&self, other: &Timestamp) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Timestamp

fn eq(&self, other: &Timestamp) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Timestamp

fn partial_cmp(&self, other: &Timestamp) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
