Struct SelectionConfig

}

Configuration for the worker selection algorithm.

Fields

strategy: SelectionStrategy

Selection strategy to use.

min_success_rate: f64

Minimum success rate (0.0-1.0) for a worker to be considered.

weights: SelectionWeightConfig

Factor weights for the balanced strategy.

fairness: FairnessConfig

Fairness settings for fair_fastest strategy.

affinity: AffinityConfig

Cache affinity settings for project-to-worker pinning.

max_load_per_core: Option<f64>

Maximum load-per-core threshold. Workers exceeding this are skipped. Set to None to disable load-based filtering.

min_free_gb: Option<f64>

Minimum free disk space in GB. Workers below this are skipped. Set to None to disable the free-space floor; per-slot disk derating still applies.

disk_gb_per_slot: f64

Disk budget in GiB per concurrent slot, after reserving min_free_gb. Must be finite and positive. Unknown disk telemetry preserves configured slots.

disk_critical_free_ratio: f64

Free-disk ratio at or below which rchd marks a worker Critical and gives it no slots (bd-xxck3). Read by rchd at startup.

disk_critical_ratio_cap_gb: Option<f64>

When set, the ratio rule above trips only while free space is also at or below this many GB, so a large disk is judged by absolute headroom (5% of 900 GB is 45 GB). Unset keeps the ratio rule unconditional.
