Struct async_raft::raft::MembershipConfig

pub struct MembershipConfig {
    pub members: HashSet<NodeId>,
    pub members_after_consensus: Option<HashSet<NodeId>>,
}

A model of the membership configuration of the cluster.

Fields

members: HashSet<NodeId>

All members of the Raft cluster.

members_after_consensus: Option<HashSet<NodeId>>

All members of the Raft cluster after joint consensus is finalized.

The presence of a value here indicates that the config is in joint consensus.

Implementations

impl MembershipConfig

pub fn all_nodes(&self) -> HashSet<u64>

Get an iterator over all nodes in the current config.

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

Check if the given NodeId exists in this membership config.

When in joint consensus, this will check both config groups.

pub fn is_in_joint_consensus(&self) -> bool

Check to see if the config is currently in joint consensus.

pub fn new_initial(id: NodeId) -> Self

Create a new initial config containing only the given node ID.

Trait Implementations

impl Clone for MembershipConfig

fn clone(&self) -> MembershipConfig

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MembershipConfig

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MembershipConfig

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl Eq for MembershipConfig

impl PartialEq<MembershipConfig> for MembershipConfig

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl Serialize for MembershipConfig

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error> where
