Struct geo_types::LineString

pub struct LineString<T>(pub Vec<Point<T>>)
 where
    T: CoordinateType;

An ordered collection of two or more Points, 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 collecting 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>

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

use geo_types::{Line, LineString, Point};

let mut points = vec![(0., 0.), (5., 0.), (7., 9.)];
let linestring: LineString<f32> = points.into_iter().collect();

let mut lines = linestring.lines();
assert_eq!(
    Some(Line::new(Point::new(0., 0.), Point::new(5., 0.))),
    lines.next()
);
assert_eq!(
    Some(Line::new(Point::new(5., 0.), Point::new(7., 9.))),
    lines.next()
);
assert!(lines.next().is_none());
