Struct HashRing 

pub struct HashRing { /* private fields */ }

Consistent hash ring for deterministic endpoint selection

Implementations

impl HashRing

pub const DEFAULT_VIRTUAL_NODES: usize = 150

Default number of virtual nodes per real endpoint

pub fn new(virtual_nodes: usize) -> Self

Create a new empty hash ring

pub fn rebuild(&mut self, endpoints: &[Arc<Endpoint>])

Rebuild the ring from the given endpoints (only healthy ones)

pub fn add_endpoint(&mut self, index: usize, endpoint_id: &str)

Add a single endpoint to the ring

pub fn remove_endpoint(&mut self, endpoint_id: &str)

Remove a single endpoint from the ring

pub fn get_endpoint(&self, key: &[u8]) -> Option<usize>

Find the endpoint index for a given key

pub fn is_empty(&self) -> bool

Returns whether the ring is empty
