Struct VectorClock 

pub struct VectorClock { /* private fields */ }

Vector clock for causality tracking

Implementations

impl VectorClock

pub fn new() -> Self

Create a new empty vector clock

pub fn increment(&mut self, node_id: &NodeId) -> u64

Increment the clock for a node

pub fn get(&self, node_id: &NodeId) -> u64

Get the clock value for a node

pub fn update(&mut self, node_id: &NodeId, value: u64)

Update clock for a node (take max)

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

Merge with another vector clock (take component-wise max)

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

Check if this clock happens-before another

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

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

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

Encode to bytes

pub fn decode(data: &[u8]) -> Option<Self>

Decode from bytes
