Struct geo_types::LineString [−][src]
pub struct LineString<T>(pub Vec<Point<T>>)
where
T: CoordinateType;
An ordered collection of two or more Point
s, representing a path between locations
Create a LineString
by calling it directly:
use geo_types::{LineString, Point}; let line = LineString(vec![Point::new(0., 0.), Point::new(10., 0.)]);
Converting a Vec
of Point
-like things:
let line: LineString<f32> = vec![(0., 0.), (10., 0.)].into();
let line: LineString<f64> = vec![[0., 0.], [10., 0.]].into();
Or collect
ing from a Point iterator
let mut points = vec![Point::new(0., 0.), Point::new(10., 0.)]; let line: LineString<f32> = points.into_iter().collect();
You can iterate over the points in the LineString
use geo_types::{LineString, Point}; let line = LineString(vec![Point::new(0., 0.), Point::new(10., 0.)]); for point in line { println!("Point x = {}, y = {}", point.x(), point.y()); }
Methods
impl<T: CoordinateType> LineString<T>
[src]
impl<T: CoordinateType> LineString<T>
pub fn lines<'a>(
&'a self
) -> impl Iterator<Item = Line<T>> + 'a
[src]
pub fn lines<'a>(
&'a self
) -> impl Iterator<Item = Line<T>> + 'a
Return an Line
iterator that yields one Line
for each line segment
in the LineString
.
Examples
