pub struct ReplicasOrdered<'a> { /* private fields */ }Expand description
Represents a sequence of replicas for a given token and strategy, ordered according to the ring order.
This container can only be created by calling ReplicaSet::into_replicas_ordered(),
and either it can borrow precomputed replica lists living in the locator (in case of SimpleStrategy)
or it must compute them on-demand (in case of NetworkTopologyStrategy).
The computation is lazy (performed by ReplicasOrderedIterator upon call to next()).
For obtaining the primary replica, no allocations are needed. Therefore, the first call
to next() is optimised and doesn not allocate.
For the remaining others, unfortunately, allocation is unevitable.
