Struct geo_types::line_string::LineString [−][src]
pub struct LineString<T>(pub Vec<Coordinate<T>>)
where
T: CoordinateType;
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); }
