Module simd_utils 

SIMD-optimized utilities for performance-critical operations.

This module provides SIMD-accelerated functions for common operations:

• String comparison
• ASCII validation
• Byte searching
• Byte counting

SIMD implementations are architecture-specific and automatically selected at compile time. Falls back to scalar implementations when SIMD is not available.

Functions

count_byte_fast

Fast count of specific byte in slice using SIMD.

fast_str_eq

Fast string comparison using SIMD when available.

find_byte_fast

Fast byte search using SIMD.

is_ascii_fast

Fast check if string contains only ASCII characters using SIMD.
