Struct VectorClock 

pub struct VectorClock { /* private fields */ }

Vector Clock — tracks the last operation seen from each actor. Used for: causal consistency, delta sync, GC.

Implementations

impl VectorClock

pub fn new() -> Self

pub fn get(&self, actor: ActorId) -> u64

pub fn advance(&mut self, actor: ActorId, ts: u64)

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

Returns true if self has seen everything other has seen.

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

Point-wise merge: take max of each component.

pub fn diff(&self, other: &VectorClock) -> Vec<(ActorId, u64, u64)>

Compute operations that other has NOT seen yet. Returns ranges (actor, from_inclusive, to_inclusive).
