Enum Role 

pub enum Role {
    Follower,
    Candidate,
    Leader,
}

Role of a Raft node (follower, candidate, or leader).

Note that the Raft paper refers to this concept as “state”. However, this crate uses the term “role” as it is more specific and less ambiguous.

Variants

Follower

Follower.

Candidate

Candidate.

Leader

Leader.

Implementations

impl Role

pub const fn is_leader(self) -> bool

Returns true if the role is leader.

pub const fn is_follower(self) -> bool

Returns true if the role is follower.

pub const fn is_candidate(self) -> bool

Returns true if the role is candidate.

Trait Implementations

impl Clone for Role

fn clone(&self) -> Role

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Role

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

Formats the value using the given formatter.

impl Hash for Role

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Role

fn eq(&self, other: &Role) -> 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.
