Struct Blockhash64 

pub struct Blockhash64(/* private fields */);

A 64-bit hash digest.

See blockhash64.

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

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

impl Hash for Blockhash64

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Blockhash64

fn cmp(&self, other: &Blockhash64) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Blockhash64

fn eq(&self, other: &Blockhash64) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Blockhash64

fn partial_cmp(&self, other: &Blockhash64) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
