Documentation

Examples

Here's some example usages:

use bk_tree::{BKTree, metrics};

// A BK-tree using the Levenshtein distance metric.
let mut tree: BKTree<&str> = BKTree::new(metrics::levenshtein);

tree.add("foo");
tree.add("bar");
tree.add("baz");
tree.add("bup");

tree.find("bar", 0); // returns vec!["bar"]
tree.find("bar", 1); // returns vec!["bar", "baz"]
tree.find("bup", 2); // returns vec!["bar", "baz", "bup"]

Benchmarks

To run benchmarks, you need to have the nightly version of Rust installed. If you do (and use multirust, for example), then you can run

multirust nightly cargo bench

to run benchmarks.
