Pointcloud

A library to find nearest neighbours in rust.

Usage

Add this to your Cargo.toml

toml [dependencies] knn = "0.1.3"

and use like this

```rust extern crate knn; use knn::PointCloud;

fn main() { let manhattan = |p: &[f64;2], q: &[f64;2]| {(q[0] - p[0]).abs() + (q[1] - p[1]).abs()}; let mut pc = PointCloud::new(manhattan); let coords = vec![[1.0, 1.0], [2.0, 2.0], [10.0, 5.0], [11.0, 15.0]]; for i in 0..coords.len() { pc.add_point(&coords[i]); }

let d = pc.get_nearest_n(&[2.1, 2.1], 2);
println!("{:?}", d)
// output :
// [(0.20000000000000018, [2.0, 2.0]), (2.2, [1.0, 1.0])]

} ```
