Struct LocalityConfig 

pub struct LocalityConfig { /* private fields */ }

Configuration for laying processes out across a failure-domain topology.

Each dimension accepts a fixed count (3) or a range (1..=3) via ProcessCount. Ranges are sampled once per seed from the simulation RNG, so every seed exercises a different cluster shape — mirroring FoundationDB’s per-seed topology generation. The total process count is the product of the four sampled dimensions.

Implementations

impl LocalityConfig

pub fn new( datacenters: impl Into<ProcessCount>, zones_per_datacenter: impl Into<ProcessCount>, machines_per_zone: impl Into<ProcessCount>, processes_per_machine: impl Into<ProcessCount>, ) -> Self

Create a topology config. Each argument is a fixed count (3) or a range (1..=3) sampled per seed.
