Struct LoomConfig 

pub struct LoomConfig {
    pub prefix: String,
    pub cpuset: Option<String>,
    pub tokio_threads: Option<usize>,
    pub rayon_threads: Option<usize>,
    pub compute_pool_size: usize,
    pub mab_knobs: Option<MabKnobs>,
    pub calibration: Option<CalibrationConfig>,
    pub prometheus_registry: Option<Registry>,
}

Configuration for the Loom runtime.

This struct can be deserialized from TOML, YAML, JSON, or environment variables using figment.

Fields

prefix: String

Thread name prefix (default: “loom”)

cpuset: Option<String>

CPU set string (e.g., “0-7,16-23”) or None for all CPUs

tokio_threads: Option<usize>

Number of tokio worker threads (default: 1)

rayon_threads: Option<usize>

Number of rayon threads (default: remaining CPUs after tokio threads)

compute_pool_size: usize

Size of compute task pool per result type (default: 64)

mab_knobs: Option<MabKnobs>

MAB scheduler configuration knobs. If None, default knobs are used.

calibration: Option<CalibrationConfig>

Calibration configuration. If None or disabled, calibration is skipped.

prometheus_registry: Option<Registry>

Prometheus registry for metrics exposition. If provided, metrics will be registered for scraping. Not serializable - must be set programmatically.

Implementations

impl LoomConfig

pub fn new() -> Self

Create a new configuration with default values.

pub fn effective_tokio_threads(&self) -> usize

Get the effective number of tokio threads.

Returns the configured value or 1 as the default.

pub fn effective_rayon_threads(&self, available_cpus: usize) -> usize

Get the effective number of rayon threads.

Returns the configured value or calculates based on available CPUs minus tokio threads.
