Struct RoundRobin 

pub struct RoundRobin { /* private fields */ }

Each in turn.

Predictable, which is worth more here than clever: with least-connections a slow instance quietly attracts less traffic and nobody notices it is slow, and with random the distribution is only even in the long run. Round-robin is wrong in exactly one way — it sends the same share to an instance that cannot cope — and the circuit breaker is what answers that.
