pub struct WeightedRoundRobinBalancer { /* private fields */ }
Expand description

Smooth Weighted Round Robin (WRR) load balancer

This balancer distributes traffic proportionally to instance weights. For example, with weights [1, 2, 3], traffic is distributed as 1:2:3.

The algorithm maintains current weights for each instance and selects the instance with the highest current weight, then reduces its weight by the total weight of all instances.
