//! Benchmarking utilities and synthetic benchmark dataset generators.
//!
//! This module contains two complementary components:
//!
//! 1. **[`performance`]** — `BenchmarkRunner`, `BenchmarkSuite`, `BenchmarkResult`,
//! `PerformanceComparison`: tools for timing dataset operations.
//!
//! 2. **[`synthetic`]** — `make_friedman1`, `make_friedman2`, `make_blobs`,
//! `make_moons`, `make_swiss_roll`, `make_checkerboard`: standard synthetic
//! benchmark datasets for regression, classification, and manifold learning.
// Re-export performance benchmarking types (preserves backwards compatibility).
