Struct HlcTimestamp 

pub struct HlcTimestamp(pub u64);

Hybrid Logical Clock for monotonic timestamps

Format: [48-bit physical time | 16-bit logical counter]

Properties:

1. Monotonically increasing
2. Causally ordered
3. Resolution: 65,536 events per millisecond

Tuple Fields

0: u64

Implementations

impl HlcTimestamp

pub fn new(physical_ms: u64, logical: u16) -> Self

Create timestamp from physical time (ms) and logical counter

pub fn physical_ms(&self) -> u64

Get physical time component (milliseconds since epoch)

pub fn logical(&self) -> u16

Get logical counter component

pub fn raw(&self) -> u64

Get raw value

pub fn allocate_next(last: &AtomicU64) -> Self

Allocate next timestamp (atomic, lock-free)

Algorithm:

1. Read current physical time
2. If physical > last_physical: reset logical to 0
3. Else: increment logical counter
4. CAS to update, retry on conflict

pub fn read_current(ts: &AtomicU64) -> Self

Read current timestamp without advancing

Trait Implementations

impl Clone for HlcTimestamp

fn clone(&self) -> HlcTimestamp

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for HlcTimestamp

impl Debug for HlcTimestamp

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

Formats the value using the given formatter.

impl Eq for HlcTimestamp

impl From<HlcTimestamp> for u64

fn from(ts: HlcTimestamp) -> Self

Converts to this type from the input type.

impl From<u64> for HlcTimestamp

fn from(val: u64) -> Self

Converts to this type from the input type.

impl Ord for HlcTimestamp

fn cmp(&self, other: &HlcTimestamp) -> 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 HlcTimestamp

fn eq(&self, other: &HlcTimestamp) -> 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 HlcTimestamp

fn partial_cmp(&self, other: &HlcTimestamp) -> 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.
