Struct StateVersion 

pub struct StateVersion {
    pub vector_clock: VectorClock,
    pub timestamp_ms: u128,
}

State version representing a causal snapshot of the system Tracks which instance is at which logical clock value

Fields

vector_clock: VectorClock

Vector clock representing this state

timestamp_ms: u128

Timestamp when this version was created (ms since UNIX epoch)

Implementations

impl StateVersion

pub fn new(vector_clock: VectorClock, timestamp_ms: u128) -> Self

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

Check if this state version causally precedes another

pub fn is_concurrent(&self, other: &StateVersion) -> bool

Check if two state versions are concurrent

pub fn causal_cmp(&self, other: &StateVersion) -> Ordering

Get causal ordering between two state versions
