Struct ClusterConfig 

pub struct ClusterConfig { /* private fields */ }

Tracks cluster members with their addresses and a monotonically increasing version

Implementations

impl ClusterConfig

pub fn new(members: Vec<(NodeId, String)>, version: u64) -> Self

Create a new cluster config with the given members and version

pub fn member_ids(&self) -> HashSet<NodeId>

Get the list of member node IDs

pub fn members(&self) -> &[(NodeId, String)]

Get all members as (node_id, address) pairs

pub fn version(&self) -> u64

Get the version of this configuration

pub fn contains(&self, node_id: NodeId) -> bool

Check if a node is a member

pub fn quorum_size(&self) -> usize

Get the majority quorum size for this config

pub fn len(&self) -> usize

Get the number of members

pub fn is_empty(&self) -> bool

Check if the config has no members

pub fn with_added_member(&self, node_id: NodeId, address: String) -> Self

Add a member to the config, returning a new config with incremented version

pub fn without_member(&self, node_id: NodeId) -> Self

Remove a member from the config, returning a new config with incremented version

Trait Implementations

impl Clone for ClusterConfig

fn clone(&self) -> ClusterConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ClusterConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for ClusterConfig

fn eq(&self, other: &ClusterConfig) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
