1//! # SIMD implementations for vector operations
2//!
3//! This module contains platform-dependent SIMD implementations of vector operations.
4//!
5//! ## CPU feature detection
6//! The system automatically determines available SIMD instructions at runtime
7//! and selects the optimal implementation.
8//!
9//! ## Supported architectures
10//! - x86/x86_64: SSE2, SSE4.1, AVX, AVX2, AVX512
11//! - ARM: NEON (AArch64)
12//! - WebAssembly: SIMD128
13//!
14//! ## Usage
15//! Users typically don't interact with this module directly,
16//! but use the high-level abstractions from `vector::traits`.
