pub trait FrechetDistance<T, Rhs = Self> {
    // Required method
    fn frechet_distance(&self, rhs: &Rhs) -> T;
}
👎Deprecated since 0.30.0: Please use the Euclidean.frechet_distance method from the geo::line_measures::FrechetDistance trait instead
Expand description

Determine the similarity between two LineStrings using the Frechet distance.

Based on Computing Discrete Frechet Distance by T. Eiter and H. Mannila.

fn frechet_distance(&self, rhs: &Rhs) -> T

👎Deprecated since 0.30.0: Please use the Euclidean.frechet_distance method from the geo::line_measures::FrechetDistance trait instead

Determine the similarity between two LineStrings using the Frechet distance.

§Examples
use geo::FrechetDistance;
use geo::line_string;

let line_string_a = line_string![
    (x: 1., y: 1.),
    (x: 2., y: 1.),
    (x: 2., y: 2.),
    (x: 3., y: 3.)
];

let line_string_b = line_string![
    (x: 2., y: 2.),
    (x: 0., y: 1.),
    (x: 2., y: 4.),
    (x: 3., y: 4.)
];

let distance = line_string_a.frechet_distance(&line_string_b);

assert_eq!(2., distance);
