pub trait Length<F: CoordFloat> {
// Required method
fn length(&self, geometry: &impl LengthMeasurable<F>) -> F;
}
Expand description
Calculate the length of a Line
, LineString
, or MultiLineString
using a given metric space.
§Examples
use geo::algorithm::line_measures::{Length, Euclidean, Haversine};
let line_string = geo::wkt!(LINESTRING(
0.0 0.0,
3.0 4.0,
3.0 5.0
));
assert_eq!(Euclidean.length(&line_string), 6.);
let line_string_lon_lat = geo::wkt!(LINESTRING (
-47.9292 -15.7801f64,
-58.4173 -34.6118,
-70.6483 -33.4489
));
assert_eq!(Haversine.length(&line_string_lon_lat).round(), 3_474_956.0);
Required Methods§

Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
