Struct TemporalWindowMatcher 

pub struct TemporalWindowMatcher {
    pub window_size: usize,
    pub stride: usize,
}

Compares two sequences of SegmentFingerprints using a sliding temporal window.

The matcher slides a window of window_size fingerprints across both sequences (with stride step), computing the average per-hash Hamming similarity for each aligned window pair.

Fields

window_size: usize

Number of segments per window.

stride: usize

Step between consecutive windows.

Implementations

impl TemporalWindowMatcher

pub fn new(window_size: usize, stride: usize) -> Self

Create a new matcher with explicit window/stride.

pub fn with_defaults() -> Self

Create a matcher with sensible defaults (window=4, stride=2).

pub fn compare_sequences( &self, a: &[SegmentFingerprint], b: &[SegmentFingerprint], ) -> f32

Compare two sequences by finding the highest-scoring window alignment.

Extracts windows from a and b and tries all combinations, returning the maximum similarity found across all window pairs.

Returns 0.0 if either sequence is shorter than window_size.

pub fn find_best_alignment( &self, a: &[SegmentFingerprint], b: &[SegmentFingerprint], ) -> Option<(usize, usize, f32)>

Find the best-aligned window pair between two sequences.

Returns Some((offset_a, offset_b, similarity)) for the best match, or None if either sequence is too short.
