Struct Results

pub struct Results { /* private fields */ }

A struct to hold the results of a Levenshtein distance calculation.

This struct contains the Levenshtein distance between two sequences and the sequence of operations (represented as a matrix of integers) that describe how to transform the first sequence into the second.

Implementations

impl Results

pub fn new(distance: i32, sequence: Vec<Vec<i32>>) -> Self

pub fn distance(&self) -> i32

Returns the Levenshtein distance.

This is the minimum number of single-character edits (insertions, deletions, or substitutions) required to change one sequence into the other.

Returns

Returns an i32 representing the Levenshtein distance.

Examples

let results = Results::new(3, vec![vec![0, 1, 2], vec![1, 2, 3]]);
assert_eq!(results.distance(), 3);

pub fn sequence(&self) -> &Vec<Vec<i32>>

Returns a reference to the sequence of operations matrix.

Each element in the matrix represents an operation code corresponding to an edit operation.

Returns

Returns a reference to a Vec<Vec<i32>> representing the sequence of operations.

Examples

let results = Results::new(3, vec![vec![0, 1, 2], vec![1, 2, 3]]);
assert_eq!(results.sequence(), &vec![vec![0, 1, 2], vec![1, 2, 3]]);
