Struct RoundRobin 

pub struct RoundRobin { /* private fields */ }

Deterministic rotating single-recipient selection.

The cursor names the next position, wraps at the current membership size, and is repaired after removal. This ordering is Bombay policy, not an actor model guarantee.

Trait Implementations

impl Clone for RoundRobin

fn clone(&self) -> RoundRobin

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RoundRobin

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

Formats the value using the given formatter.

impl Default for RoundRobin

fn default() -> RoundRobin

Returns the “default value” for a type.

impl PartialEq for RoundRobin

fn eq(&self, other: &RoundRobin) -> 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<Route: DeliveryRoute + Clone + PartialEq> RoutingStrategy<Route> for RoundRobin

type Observation = Never

Closed observation type accepted by this policy.

type Error = Never

Concrete observation rejection reason.

fn select( &mut self, members: &[Route], _: &<Route::Protocol as Protocol>::Msg, ) -> Option<usize>

Select at most one index from this exact typed membership snapshot.

fn observe( &mut self, _: &[Route], observation: Never, ) -> Result<(), RoutingObservationRejection<Never, Never>>

Fold one typed observation against the same membership snapshot.

fn removed(&mut self, index: usize, _: Route, remaining: usize)

Repair policy-local position after a membership removal.

fn added(&mut self, _recipient: Route)

Update policy-local state after one new membership is committed.
