Struct Member

pub struct Member<T> { /* private fields */ }

A Cluster Member. Also often called “cluster update”.

A Member represents Foca’s snapshot knowledge about an crate::Identity. An individual cluster update is simply a serialized Member which other Foca instances receive and use to update their own cluster state representation.

Implementations

impl<T> Member<T>

pub fn new(id: T, incarnation: Incarnation, state: State) -> Self

Initializes a new member.

id is an identity used to uniquely identify an individual cluster member (say, a primary key).

pub fn alive(id: T) -> Self

Shortcut for initializing a member as State::Alive.

pub fn incarnation(&self) -> Incarnation

Getter for the member’s Incarnation

pub fn state(&self) -> State

Getter for the member’s State

pub fn id(&self) -> &T

Getter for the member’s identity

Trait Implementations

impl<T: Clone> Clone for Member<T>

fn clone(&self) -> Member<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Member<T>

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

Formats the value using the given formatter.

impl<'de, T> Deserialize<'de> for Member<T>

where T: Deserialize<'de>,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T: PartialEq> PartialEq for Member<T>

fn eq(&self, other: &Member<T>) -> 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.

impl<T> Serialize for Member<T>

where T: Serialize,

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
