Struct FrameHash 

pub struct FrameHash {
    pub algorithm: HashAlgorithm,
    pub bits: Vec<u8>,
    pub frame_index: u64,
}

A compact hash value representing one video frame.

Fields

algorithm: HashAlgorithm

Algorithm that produced this hash.

bits: Vec<u8>

Raw hash bits stored as a byte vector.

frame_index: u64

Frame index within the source media.

Implementations

impl FrameHash

pub fn new(algorithm: HashAlgorithm, bits: Vec<u8>, frame_index: u64) -> Self

Construct a new FrameHash.

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

Compute the Hamming distance between self and other.

Returns None if the two hashes have different algorithms or lengths.

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

Return true if the two hashes are within max_distance bits of each other.

pub fn byte_len(&self) -> usize

Return the number of bytes in the hash.

Trait Implementations

impl Clone for FrameHash

fn clone(&self) -> FrameHash

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FrameHash

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

Formats the value using the given formatter.

impl Eq for FrameHash

impl Hash for FrameHash

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 FrameHash

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