Struct Fingerprint 

pub struct Fingerprint {
    pub whole: Hash256,
    pub windows: Vec<WindowFp>,
}

A whole-document fingerprint plus overlapping window fingerprints.

Fields

whole: Hash256

windows: Vec<WindowFp>

Implementations

impl Fingerprint

pub fn compute(text: &str) -> Self

Compute the fingerprint of text.

pub fn best_distance(&self, candidate: &Hash256) -> u32

The best (smallest) Hamming distance from candidate’s whole-document hash to this fingerprint’s whole hash or any of its window hashes.

pub fn matches(&self, candidate: &Hash256) -> bool

Whether candidate’s whole-document hash matches this fingerprint (whole or any window) within MATCH_THRESHOLD.
