Struct VectorClock 

pub struct VectorClock { /* private fields */ }

Vector clock: maps peer IDs to their latest known counter.

On handshake, the edge sends its clock to Origin. Origin compares against its own clock and sends back deltas for any peer whose counter is ahead of the edge’s view.

Implementations

impl VectorClock

pub fn new() -> Self

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

Set the counter for a peer.

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

Get the counter for a peer (0 if unknown).

pub fn advance(&mut self, peer_id: u64, counter: u64)

Advance a peer’s counter if the new value is greater.

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

Merge another clock into this one (take max per peer).

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

Check if this clock dominates another (all entries >= other’s).

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

Compute which peers have advanced beyond our knowledge.

Returns (peer_id, their_counter, our_counter) for peers where remote is ahead of self.

pub fn to_wire(&self) -> HashMap<String, u64>

Export as a map of peer_id_hex → counter for wire format.

pub fn from_wire(wire: &HashMap<String, u64>) -> Self

Import from wire format peer_id_hex → counter.

pub fn peer_count(&self) -> usize

Number of peers tracked.

pub fn peers(&self) -> Vec<u64>

All tracked peer IDs.

pub fn as_map(&self) -> &HashMap<u64, u64>

Export as HashMap<u64, u64> for direct access.
