Struct FilenameMatcher 

pub struct FilenameMatcher { /* private fields */ }

Normalized filename / title matcher for media deduplication.

Strips common media-file noise (resolution tags, codec names, release-group markers, punctuation) and computes a combined similarity from Levenshtein edit distance, token Jaccard, and bigram Dice coefficient.

Implementations

impl FilenameMatcher

pub fn new(threshold: f64) -> Self

Create a new matcher with default weights.

pub fn with_weights( threshold: f64, edit_w: f64, token_w: f64, bigram_w: f64, ) -> Self

Create with custom weights. Weights are normalized internally.

pub fn normalize(name: &str) -> String

Normalize a filename/title for comparison.

Strips extension, converts to lowercase, removes common noise tokens (resolution tags, codec names, quality markers), and collapses whitespace.

pub fn similarity(&self, name_a: &str, name_b: &str) -> FuzzyScore

Compute the combined similarity score between two filenames/titles.

pub fn is_match(&self, name_a: &str, name_b: &str) -> bool

Returns true if the two filenames are considered matching.

pub fn find_matching_pairs( &self, names: &[&str], ) -> Vec<(usize, usize, FuzzyScore)>

Find all matching pairs within a list of filenames.

Returns Vec<(usize, usize, FuzzyScore)> with i < j.

pub fn threshold(&self) -> f64

Return the threshold.

Trait Implementations

impl Default for FilenameMatcher

fn default() -> Self

Returns the “default value” for a type.
