Struct Timestamp 

pub struct Timestamp { /* private fields */ }

§7.2: 48-bit milliseconds, a 16-bit counter, and a 64-bit device id, ordered in that order. No clock is read here.

Implementations

impl Timestamp

pub const MAX_MILLISECONDS: u64

The greatest millisecond the timestamp can represent.

pub fn new( milliseconds: u64, counter: u16, device: DeviceId, ) -> Result<Self, MergeError>

Construct a timestamp, refusing milliseconds outside its 48-bit range.

pub fn next( latest: Option<Self>, clock_ms: u64, device: DeviceId, ) -> Result<Self, MergeError>

Stamp a local write or entry after the latest timestamp from local work and applied incoming work. The caller persists that latest timestamp. A counter overflow advances the millisecond; exhaustion is an error.

pub fn milliseconds(self) -> u64

The wall-clock part, in milliseconds.

pub fn counter(self) -> u16

The logical counter within the millisecond.

pub fn device(self) -> DeviceId

The writing device’s id.

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 Debug for Timestamp

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

Formats the value using the given formatter.

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.
