[−][src]Trait rstar::RTreeNum

pub trait RTreeNum: Bounded + Num + Clone + Copy + Signed + PartialOrd + Debug { }

Defines a number type that is compatible with rstar.

rstar works out of the box with the following standard library types:

  • i32
  • i64
  • f32
  • f64

This type cannot be implemented directly. Instead, it is just required to implement all required traits from the num_traits crate.

Example

use num_traits::{Bounded, Num, Signed};

#[derive(Clone, Copy, PartialEq, PartialOrd, Debug)]
struct MyFancyNumberType(f32);

impl Bounded for MyFancyNumberType {
  // ... details hidden ...
}

impl Signed for MyFancyNumberType {
  // ... details hidden ...
}

impl Num for MyFancyNumberType {
  // ... details hidden ...
}

// There's a lot of traits that are still missing to make the above code compile,
// let's assume they are implemented. MyFancyNumberType type now readily implements
// RTreeNum and can be used with r-trees:
use rstar::RTree;
let mut rtree = RTree::new();
rtree.insert([MyFancyNumberType(0.0), MyFancyNumberType(0.0)]);
