Struct FuzzyMatcher 

pub struct FuzzyMatcher { /* private fields */ }

Fuzzy matcher instance. Holds memory for the state of the fuzzy matcher so that large batches of queries can be processed with minimal allocations. When performing a large batch of fuzzy match queries, use a common instance of this struct to improve performance by avoiding extra allocations.

Implementations

impl FuzzyMatcher

pub fn new() -> Self

Creates a new instance of a fuzzy matcher.

pub fn fuzzy_match(&mut self, target: &str, query: &str) -> Option<usize>

Fuzzy match a string against a query string. Returns a score that is higher for a more confident match, or None if the query does not match the target string.

Examples

let mut matcher = code_fuzzy_match::FuzzyMatcher::new();
let matches = matcher.fuzzy_match("the quick brown fox", "bro fox");
assert!(matches.is_some());
let no_match = matcher.fuzzy_match("the quick brown fox", "cat");
assert!(no_match.is_none());

let high_score = matcher.fuzzy_match("Example string", "example");
let lower_score = matcher.fuzzy_match("Example string", "str");
assert!(high_score.unwrap() > lower_score.unwrap());
