Module simd 

SIMD capability detection and runtime optimization. SIMD capability detection and runtime optimization.

This module provides runtime detection of CPU SIMD features to enable performance warnings and feature-appropriate code paths.

Example

use edgevec::simd::{capabilities, warn_if_suboptimal, SimdCapabilities};

// Get detected capabilities
let caps = capabilities();
println!("AVX2 available: {}", caps.avx2);

// Check if configuration is optimal
if !caps.is_optimal() {
    // Warn user about performance impact
    warn_if_suboptimal();
}

Backend Selection

use edgevec::simd::{select_backend, SimdBackend};

let backend = select_backend();
match backend {
    SimdBackend::Avx2 => println!("Using AVX2 (256-bit)"),
    SimdBackend::Avx => println!("Using AVX (256-bit)"),
    SimdBackend::Sse41 => println!("Using SSE4.1 (128-bit)"),
    SimdBackend::Neon => println!("Using NEON (128-bit)"),
    SimdBackend::Portable => println!("Using portable fallback"),
}
