Struct VectorClock 

pub struct VectorClock { /* private fields */ }

Available on crate feature extensions only.

A vector clock for causality tracking

Implementations

impl VectorClock

pub fn new() -> Self

Create empty vector clock

pub fn increment(&mut self, participant: &str)

Increment counter for a participant

pub fn get(&self, participant: &str) -> u64

Get counter for a participant

pub fn set(&mut self, participant: String, counter: u64)

Set counter for a participant

pub fn merge(&mut self, other: &VectorClock)

Merge with another vector clock (take max of each entry)

pub fn happens_before(&self, other: &VectorClock) -> bool

Check if this clock happens-before another

pub fn is_concurrent_with(&self, other: &VectorClock) -> bool

Check if two clocks are concurrent (neither happens-before the other)

pub fn len(&self) -> usize

Number of entries

pub fn is_empty(&self) -> bool

Check if empty

pub fn iter(&self) -> impl Iterator<Item = (&String, &u64)>

Iterate over entries

pub fn encode(&self) -> Vec<u8>

Encode to bytes

pub fn decode(data: &[u8]) -> Result<(Self, usize), NegotiationError>

Decode from bytes

Trait Implementations

impl Clone for VectorClock

fn clone(&self) -> VectorClock

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VectorClock

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

Formats the value using the given formatter.

impl Default for VectorClock

fn default() -> VectorClock

Returns the “default value” for a type.

impl PartialEq for VectorClock

fn eq(&self, other: &VectorClock) -> 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.
