Function compute_statistics 

pub fn compute_statistics(
    results: &[BenchExecutionResult],
    _config: &ExecutionConfig,
) -> Vec<(String, Option<SummaryStatistics>)>

Compute statistics for benchmark results (parallelized with Rayon)

Uses Rayon for parallel computation of summary statistics across all benchmarks. Each benchmark’s samples are independently processed, making this highly parallelizable.

Arguments

• results - Benchmark execution results containing samples
• _config - Execution configuration. Currently unused but reserved for future extensions such as configurable outlier detection methods, custom percentile thresholds, or alternative statistical algorithms.

Returns

Vector of (benchmark_id, optional statistics) pairs. Returns None for benchmarks with no samples (e.g., crashed or skipped benchmarks).
