Function hamming_distance_slice 

pub fn hamming_distance_slice(a: &[u8], b: &[u8]) -> u32

Computes Hamming distance for arbitrary-length byte slices.

Algorithm

1. XOR each byte pair to find differing bits
2. Count set bits using count_ones()
3. Sum across all bytes

Arguments

• a - First byte slice
• b - Second byte slice (must be same length as a)

Returns

The number of differing bits

Panics

Panics if slices have different lengths.

Example

use edgevec::quantization::simd::portable::hamming_distance_slice;

let a = [0xAA; 32];
let b = [0x55; 32];

let distance = hamming_distance_slice(&a, &b);
assert_eq!(distance, 256); // All bits differ (32 * 8)
