Examples

Creating a Polyline

use shapefile::{Point, Polyline};
let points = vec![
    Point::new(1.0, 1.0),
    Point::new(2.0, 2.0),
];
let poly = Polyline::new(points, vec![0]);

Trait Implementations

impl<PointType> MultipointShape<PointType> for GenericPolyline<PointType>

fn point<I: SliceIndex<[PointType]>>(
    &self,
    index: I
) -> Option<&<I as SliceIndex<[PointType]>>::Output>

fn points(&self) -> &[PointType]

Returns a non mutable slice to the points

impl<PointType> MultipartShape<PointType> for GenericPolyline<PointType>

fn parts_indices(&self) -> &[i32]

Returns a non mutable slice of the parts as written in the file:

fn part(&self, index: usize) -> Option<&[PointType]>

Returns the slice of points corresponding to part n°ìndex if the shape actually has multiple parts
