Struct ExecutorConfig 

pub struct ExecutorConfig {
    pub worker_threads: usize,
    pub async_threads: usize,
    pub max_global_queue_size: usize,
    pub local_queue_initial_capacity: usize,
    pub thread_name_prefix: String,

    pub memory: MemoryConfig,
    pub cleanup: CleanupConfig,
}

Configuration settings for executor behavior and performance characteristics.

This struct encapsulates all tunable parameters that affect executor operation, including thread pool sizes, queue capacities, and various performance optimizations.

Fields

worker_threads: usize

Number of worker threads for parallel tasks

async_threads: usize

Number of threads dedicated to async tasks

max_global_queue_size: usize

Maximum aggregate size of the workers’ external admission queues.

Executor construction partitions this bound across workers without exceeding it. The value must supply at least two slots per worker.

local_queue_initial_capacity: usize

Initial slot count for each resizable per-worker local priority queue.

Values below the deque minimum normalize upward. Local queues grow when full; Self::max_global_queue_size is the external admission bound.

thread_name_prefix: String

Thread name prefix for worker threads

worker_placement: WorkerPlacement

Whether each worker is confined to one logical processor.

WorkerPlacement::Pinned can fail executor construction; see ExecutorError::WorkerPlacementFailed.

enable_metrics: bool

Whether to enable metrics collection

preemption: PreemptionConfig

Task preemption configuration

memory: MemoryConfig

Memory management configuration

cleanup: CleanupConfig

Task cleanup configuration

Trait Implementations

impl Default for ExecutorConfig

fn default() -> ExecutorConfig
