Struct SegmentFingerprint 

pub struct SegmentFingerprint {
    pub hash: u64,
    pub frame_count: usize,
    pub duration_ms: u64,
}

A compact fingerprint for a single video segment (group of frames).

Fields

hash: u64

Perceptual hash of the segment (64-bit).

frame_count: usize

Number of frames in this segment.

duration_ms: u64

Duration of this segment in milliseconds.

Implementations

impl SegmentFingerprint

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

Create a SegmentFingerprint from pre-computed values.

pub fn from_frame_data( data: &[u8], frame_count: usize, duration_ms: u64, ) -> Self

Derive a SegmentFingerprint from raw frame data.

Uses a two-pass FNV-1a–based perceptual hash that is sensitive to the distribution of byte values (luminance-like) rather than the exact raw bytes, giving some robustness to minor encoding differences.

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

Compute the Hamming distance (number of differing bits) between two hashes.

pub fn ms_per_frame(&self) -> u64

Returns the average milliseconds per frame.

Returns 0 if frame_count is zero.

Trait Implementations

impl Clone for SegmentFingerprint

fn clone(&self) -> SegmentFingerprint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SegmentFingerprint

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

Formats the value using the given formatter.

impl Eq for SegmentFingerprint

impl PartialEq for SegmentFingerprint

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