Struct HlcTimestamp 

pub struct HlcTimestamp { /* private fields */ }

Hybrid Logical Clock timestamp.

Layout (12 bytes):

• wall_time: i64 — nanoseconds since Unix epoch (true nanosecond precision)
• logical: i32 — counter for events within the same nanosecond

Comparison: wall_time first, then logical (total order). Big-endian byte serialization preserves comparison order for non-negative values.

Range:

• wall_time: covers ~292 years from epoch (until year 2262)
• logical: up to 2,147,483,647 events per nanosecond

Implementations

impl HlcTimestamp

pub const ZERO: Self

pub fn new(wall_time_ns: i64, logical: i32) -> Self

Create from wall-clock time in nanoseconds and logical counter.

pub fn wall_time(&self) -> i64

Wall-clock time in nanoseconds since Unix epoch.

pub fn logical(&self) -> i32

Logical counter.

pub fn to_bytes(&self) -> [u8; 12]

Serialize to 12 bytes big-endian (preserves comparison order for non-negative values).

pub fn from_bytes(b: &[u8; 12]) -> Self

Reconstruct from 12 bytes big-endian.

pub fn is_zero(&self) -> bool

Returns true if this is the zero/uninitialized timestamp.

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 Display for HlcTimestamp

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

Formats the value using the given formatter.

impl Hash for HlcTimestamp

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 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.
