Trait shapefile::record::traits::HasXY [−][src]
Trait to access the x, and y values of a point
Examples
use shapefile::record::traits::HasXY; use shapefile::{Point, NO_DATA, PointZ}; fn mean_x_y<PointType: HasXY>(points: &[PointType]) -> (f64, f64) { let (sum_x, sum_y) = points.iter() .fold((0.0, 0.0), |acc, point| (acc.0 + point.x(), acc.1 + point.y())); (sum_x / points.len() as f64, sum_y / points.len() as f64) } let points = vec![PointZ::new(1.0, 2.0, 3.0, NO_DATA), PointZ::new(1.0, 2.0, 5.0, NO_DATA)]; assert_eq!(mean_x_y(&points), (1.0, 2.0));
