Existence Queries

We can use contains to decide whether a point is already inserted to the tree or not. Here is an example:

use rstar::RTree;

fn main() {
    let tree = RTree::bulk_load(vec![(0, 0), (1, 2), (8, 5)]);

    println!("{}", tree.contains(&(1, 2)));
    println!("{}", tree.contains(&(100, 100)));
}

Output:

true
false
