Struct raft::Configuration

pub struct Configuration { /* fields omitted */ }

A Raft internal representation of a Configuration.

This is corollary to a ConfState, but optimized for contains calls.

Methods

impl Configuration

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

The voter set.

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

The learner set.

impl Configuration

pub fn new(
    voters: impl IntoIterator<Item = u64>,
    learners: impl IntoIterator<Item = u64>
) -> Self

Create a new configuration with the given configuration.

impl Configuration

pub fn valid(&self) -> Result<()>

Validates that the configuration is not problematic.

Namely:

• There can be no overlap of voters and learners.
• There must be at least one voter.

pub fn contains(&self, id: u64) -> bool

Returns whether or not the given id is a member of this configuration.

Trait Implementations

impl Clone for Configuration

fn clone(&self) -> Configuration

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for Configuration

fn default() -> Configuration

Returns the "default value" for a type.

impl<Iter1, Iter2> From<(Iter1, Iter2)> for Configuration where
    Iter1: IntoIterator<Item = u64>,
    Iter2: IntoIterator<Item = u64>, 

fn from((voters, learners): (Iter1, Iter2)) -> Self

Performs the conversion.

impl From<ConfState> for Configuration

fn from(conf_state: ConfState) -> Self

Performs the conversion.

impl From<Configuration> for ConfState

fn from(conf: Configuration) -> Self

Performs the conversion.

impl PartialEq<Configuration> for Configuration

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

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

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

This method tests for !=.

impl Debug for Configuration

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

Formats the value using the given formatter.
