pub struct Blockhash64(_);

A 64-bit hash digest.

Implementations

impl Blockhash64

pub fn distance(&self, other: &Self) -> u32

Returns the Hamming distance between two hashes.

Examples

use blockhash::Blockhash64;

let a = Blockhash64::from([

let b = Blockhash64::from([
    0xd0, 0xad, 0xbe, 0xef, 0xde, 0xad, 0xbe, 0xff,
]);

assert_eq!(a.distance(&b), 4);
