Crate phasesmith_execution 

Explicit bounded execution contexts for native PhaseSmith kernels.

This crate owns reusable Rayon pools instead of installing or modifying the process-global pool. It gives desktop applications, services, Python adapters, and tests the same deterministic worker-budget contract. Applications normally use it through phasesmith::execution.

Example

use phasesmith_execution::ExecutionPolicy;

let policy = ExecutionPolicy::new(Some(4), 2)?;
let results = policy.context().map_ordered(4, 2, |index| index * index);
assert_eq!(results, [0, 1, 4, 9]);
assert!(policy.resolved_budget() >= 1);

requested_threads = None selects available logical parallelism. Fixed requests are capped to what the process reports as available. Work below minimum_parallel_tasks remains serial, and ordered mapping always returns results in input order.

Structs

ExecutionContext

Reusable, operation-owned worker pool with deterministic ordered mapping.

ExecutionPolicy

Immutable worker-budget policy with one persistent bounded execution pool.

Enums

ExecutionPolicyError

Invalid or unconstructable native execution policy.

Constants

DEFAULT_EXECUTION_THREADS

Default fixed worker budget used by scripts and applications.

DEFAULT_MINIMUM_PARALLEL_TASKS

Default number of independent tasks required before parallel scheduling.
