Struct PerceptualHash 

pub struct PerceptualHash(pub u64);

A 64-bit perceptual hash stored as a u64 bitmask.

Tuple Fields

0: u64

Implementations

impl PerceptualHash

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

Hamming distance to another perceptual hash.

Two images are considered visually similar when the distance is ≤ 10.

pub fn is_similar(self, other: Self, threshold: u32) -> bool

Whether two hashes are perceptually similar (distance ≤ threshold).

pub fn to_hex(self) -> String

Hexadecimal representation (16 characters).

pub fn from_hex(s: &str) -> Option<Self>

Parse a hex string produced by PerceptualHash::to_hex.

Errors

Returns None on invalid hex input.

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 Display for PerceptualHash

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

Formats the value using the given formatter.

impl Hash for PerceptualHash

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 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.
