Enum HashAlgorithm 

pub enum HashAlgorithm {
    DHash64,
    PHash64,
    AHash128,
    WHash256,
}

Hashing algorithm used to produce a frame hash.

Variants

DHash64

64-bit difference hash (dHash).

PHash64

64-bit perceptual hash (pHash).

AHash128

128-bit average hash.

WHash256

256-bit wavelet hash.

Implementations

impl HashAlgorithm

pub const fn bit_length(self) -> u32

Return the bit length of the hash produced by this algorithm.

pub const fn is_perceptual(self) -> bool

Whether this algorithm is considered a perceptual hash.

pub const fn name(self) -> &'static str

Return a human-readable name for the algorithm.

Trait Implementations

impl Clone for HashAlgorithm

fn clone(&self) -> HashAlgorithm

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for HashAlgorithm

impl Debug for HashAlgorithm

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

Formats the value using the given formatter.

impl Eq for HashAlgorithm

impl Hash for HashAlgorithm

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 HashAlgorithm

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