Struct PerceptualHash 

pub struct PerceptualHash { /* private fields */ }

Perceptual hash result.

Implementations

impl PerceptualHash

pub fn new(hash: u64, bits: usize) -> Self

Create from hash value.

pub fn hash(&self) -> u64

Get hash value.

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

Calculate Hamming distance.

pub fn similarity(&self, other: &Self) -> f64

Calculate similarity (0.0-1.0).

pub fn to_hex(&self) -> String

Convert to hex string.

Trait Implementations

impl Clone for PerceptualHash

fn clone(&self) -> PerceptualHash

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PerceptualHash

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for PerceptualHash

impl PartialEq for PerceptualHash

fn eq(&self, other: &PerceptualHash) -> 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.
