Fields§

§version: u64

Rendezvous version (epoch) after the event.

§world_size: usize

World size after the event.

§members: Vec<usize>

Sorted membership after the event.

§shard_assignment: Vec<ShardRange>

Balanced contiguous shard assignment for this membership.

§scaled_lr: f64

Linear-scaling-rule learning rate for this world size.

§averaging_factor: f64

Gradient-averaging factor (1 / world_size) for this world size.
