[−][src]Struct geo_types::LineString
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::{Coordinate, LineString}; 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::{Coordinate, LineString}; 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::{Coordinate, LineString}; 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); }
You can also iterate over the coordinates in the LineString
as Point
s:
use geo_types::{Coordinate, LineString}; let line_string = LineString(vec![ Coordinate { x: 0., y: 0. }, Coordinate { x: 10., y: 0. }, ]); for point in line_string.points_iter() { println!("Point x = {}, y = {}", point.x(), point.y()); }
Methods
impl<T: CoordinateType> LineString<T>
[src]
pub fn points_iter(&self) -> PointsIter<T>
[src]
Return an iterator yielding the coordinates of a LineString
as Point
s
pub fn into_points(self) -> Vec<Point<T>>
[src]
Return the coordinates of a LineString
as a Vec
of Point
s
pub fn lines<'a>(
&'a self
) -> impl ExactSizeIterator + Iterator<Item = Line<T>> + 'a
[src]
&'a self
) -> impl ExactSizeIterator + Iterator<Item = Line<T>> + 'a
Return an iterator yielding one Line
for each line segment
in the LineString
.
Examples
use geo_types::{Coordinate, Line, LineString}; let mut coords = vec![(0., 0.), (5., 0.), (7., 9.)]; let line_string: LineString<f32> = coords.into_iter().collect(); let mut lines = line_string.lines(); assert_eq!( Some(Line::new( Coordinate { x: 0., y: 0. }, Coordinate { x: 5., y: 0. } )), lines.next() ); assert_eq!( Some(Line::new( Coordinate { x: 5., y: 0. }, Coordinate { x: 7., y: 9. } )), lines.next() ); assert!(lines.next().is_none());
pub fn triangles<'a>(
&'a self
) -> impl ExactSizeIterator + Iterator<Item = Triangle<T>> + 'a
[src]
&'a self
) -> impl ExactSizeIterator + Iterator<Item = Triangle<T>> + 'a
An iterator which yields the coordinates of a LineString
as Triangle
s
pub fn num_coords(&self) -> usize
[src]
Return the number of coordinates in the LineString
.
Examples
use geo_types::LineString; let mut coords = vec![(0., 0.), (5., 0.), (7., 9.)]; let line_string: LineString<f32> = coords.into_iter().collect(); assert_eq!(3, line_string.num_coords());
