[−][src]Trait geo::algorithm::frechet_distance::FrechetDistance

pub trait FrechetDistance<T, Rhs = Self> {
    fn frechet_distance(&self, rhs: &Rhs) -> T;
}

Determine the similarity between two LineStrings using the Frechet distance.

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

Required methods

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

Determine the similarity between two LineStrings using the Frechet distance.

Examples

use geo::LineString;
use geo::algorithm::frechet_distance::FrechetDistance;

let ls_a = LineString::from(vec![(1., 1.), (2., 1.), (2., 2.), (3., 3.)]);
let ls_b = LineString::from(vec![(2., 2.), (0., 1.), (2., 4.), (3., 4.)]);

let distance = ls_a.frechet_distance(&ls_b);

assert_eq!(2., distance);
