Struct HlcTimestamp 

pub struct HlcTimestamp {
    pub wall_time_ms: i64,
    pub counter: u32,
    pub node_id: u32,
}

A Hybrid Logical Clock timestamp.

Ordering: (wall_time, counter, node_id) — fully deterministic. Two HLC timestamps from different nodes are never equal.

Fields

wall_time_ms: i64

Wall clock component (milliseconds since Unix epoch)

counter: u32

Logical counter — incremented when wall clock hasn’t advanced

node_id: u32

Node that generated this timestamp (0 for centralized mode)

Implementations

impl HlcTimestamp

pub fn new(wall_time_ms: i64, counter: u32, node_id: u32) -> Self

Create a timestamp from components.

pub fn to_datetime(&self) -> DateTime<Utc>

Convert to a chrono DateTime (loses counter and node_id precision).

pub fn from_datetime(dt: DateTime<Utc>) -> Self

Create from a chrono DateTime (sets counter=0, node_id=0).

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 Debug for HlcTimestamp

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for HlcTimestamp

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for HlcTimestamp

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

Formats the value using the given formatter.

impl Ord for HlcTimestamp

fn cmp(&self, other: &Self) -> 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: &Self) -> 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.

impl Serialize for HlcTimestamp

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
