Struct HybridTimestamp 

pub struct HybridTimestamp {
    pub physical: u64,
    pub logical: u16,
    pub node_id: u16,
}

A timestamp from a Hybrid Logical Clock.

Consists of:

• physical: milliseconds since Unix epoch (or any monotonic source)
• logical: counter for events within the same physical millisecond
• node_id: tiebreaker to ensure total ordering across nodes (lower 16 bits of NodeId)

Total size: 12 bytes (u64 + u16 + u16).

Note: node_id uses only 16 bits for compact timestamps. When constructing from a NodeId (u64), only the lower 16 bits are used for tiebreaking. This is sufficient for up to 65 535 concurrent nodes.

Fields

physical: u64

Physical time component (milliseconds).

logical: u16

Logical counter for same-millisecond ordering.

node_id: u16

Node identifier for deterministic tiebreaking (lower 16 bits of NodeId).

Implementations

impl HybridTimestamp

pub fn zero() -> Self

Create a zero timestamp.

pub fn to_u128(&self) -> u128

Pack into a u128 for efficient comparison and storage. Layout: [physical: 64 bits][logical: 16 bits][node_id: 16 bits][reserved: 32 bits]

Trait Implementations

impl Clone for HybridTimestamp

fn clone(&self) -> HybridTimestamp

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HybridTimestamp

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

Formats the value using the given formatter.

impl Hash for HybridTimestamp

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 HybridTimestamp

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 HybridTimestamp

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

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.
