Struct lfchring::VirtualNode

pub struct VirtualNode<N: ?Sized> where
    N: Node,  { /* fields omitted */ }

A type to represent a single virtual node of a distinct Node in the consistent hashing ring.

Implementations

impl<N: ?Sized> VirtualNode<N> where
    N: Node, 

pub fn replica_owners(&self) -> &[Arc<N>]

Returns a slice of Nodes, each wrapped in an Arc, which own a replica for the keys that are assigned on the VirtualNode<N> at hand.

The Nodes are returned according to their order in the consistent hashing ring. Therefore, the first Node is always the one that the particular VirtualNode originally belongs to.

impl<N: ?Sized> Clone for VirtualNode<N> where
    N: Node, 

fn clone(&self) -> Self

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)
