Struct geo_types::line_string::LineString
source · pub struct LineString<T>(pub Vec<Coordinate<T>>)
where
T: CoordinateType;
Expand description
An ordered collection of two or more Coordinate
s, representing a
path between locations.
Examples
Create a LineString
by calling it directly:
use geo_types::{LineString, Coordinate};
let line_string = LineString(vec![
Coordinate { x: 0., y: 0. },
Coordinate { x: 10., y: 0. },
]);
Converting a Vec
of Coordinate
-like things:
use geo_types::LineString;
let line_string: LineString<f32> = vec![
(0., 0.),
(10., 0.),
].into();
use geo_types::LineString;
let line_string: LineString<f64> = vec![
[0., 0.],
[10., 0.],
].into();
Or collect
ing from a Coordinate
iterator
use geo_types::{LineString, Coordinate};
let mut coords_iter = vec![
Coordinate { x: 0., y: 0. },
Coordinate { x: 10., y: 0. }
].into_iter();
let line_string: LineString<f32> = coords_iter.collect();
You can iterate over the coordinates in the LineString
:
use geo_types::{LineString, Coordinate};
let line_string = LineString(vec![
Coordinate { x: 0., y: 0. },
Coordinate { x: 10., y: 0. },
]);
for coord in line_string {
println!("Coordinate x = {}, y = {}", coord.x, coord.y);
}

for each line segment
in the LineString
.
