Module rayon_parallel 

Rayon parallel profiling. Spec section 4.9. Measures parallel efficiency, work stealing, and load balance (Heijunka score).

Structs

RayonProfile

Rayon parallel profile output.

ScalingPoint

A single point in a parallel scaling curve.

Functions

profile_parallel

Profile a parallel function. Runs the benchmark binary with RAYON_NUM_THREADS=1 and RAYON_NUM_THREADS=N, using min-of-3 timing for stability. Computes parallel metrics.

profile_scaling

Parallel scaling sweep — measure throughput at each thread count. Produces the scaling table used in spec Appendix A.2.
