Struct ConsistentHashRing 

pub struct ConsistentHashRing { /* private fields */ }

Consistent hash ring for PID-to-node assignment.

Uses virtual nodes for even distribution across cluster members. When the cluster feature is enabled, this delegates to ruvector_cluster::ConsistentHashRing under the hood; otherwise a standalone implementation is provided so the mesh module can still compile without the full cluster dependency.

Implementations

impl ConsistentHashRing

pub fn new(virtual_nodes: usize) -> Self

Create a new hash ring with the given number of virtual nodes per real node. Higher values give more even distribution.

pub fn add_node(&mut self, node_id: &str)

Add a node to the ring.

pub fn remove_node(&mut self, node_id: &str)

Remove a node from the ring.

pub fn assign(&self, pid: u64) -> Option<&str>

Find which node owns a given PID (clockwise walk).

pub fn node_count(&self) -> usize

Number of distinct real nodes in the ring.
