Struct contour::Line

pub struct Line { /* private fields */ }

A line has the geometry and threshold of a contour ring, built by [ContourBuilder].

Implementations

impl Line

pub fn geometry(&self) -> &MultiLineString<Float>

Borrow the MultiLineString geometry of this contour.

pub fn into_inner(self) -> (MultiLineString<Float>, Float)

Get the owned lines and threshold of this contour.

pub fn threshold(&self) -> Float

Get the threshold used to construct this isoline.

pub fn to_geojson(&self) -> Feature

Available on crate feature geojson only.

Convert the line to a struct from the geojson crate.

To get a string representation, call to_geojson().to_string().

use contour::ContourBuilder;

let builder = ContourBuilder::new(10, 10, false);
let contours = builder.lines(&[
// ...ellided for brevity
], &[0.5]).unwrap();

let geojson_string = contours[0].to_geojson().to_string();

assert_eq!(&geojson_string[0..27], r#"{"geometry":{"coordinates":"#);
