Struct fuzzy_match::algorithms::SorensenDice

pub struct SorensenDice(_);

Sorensen-Dice coefficient algorithm.

Trait Implementations

impl SimilarityAlgorithm for SorensenDice

fn new() -> SorensenDice

Create a new instance of this algorithm. It's recommended to keep a single instance around as long as possible, as this allows any temporary storage to be recycled without additional allocations.

fn get_similarity(&mut self, a: &str, b: &str) -> f32

Gets the similarity of a given pair of strings using this algorithm. Two identical strings will always produce 1.0, and mismatching length 1 strings produce 0.0. If either string is empty, 0.0 will be returned. Implementations within the crate round the weight to 5 decimal places, but other implementations don't need to do the same.
