Crates.io Docs.rs Build Status

This is a fork of nabo, which implements support for periodic boundaries in a very efficient manner. The API has changed minimally. The original README from Stéphane Magnenat & Hannes Sommer is attached below:

Overview

nabo is a fast K Nearest Neighbour (KNN) library for low-dimensional spaces. It is a re-implementation in pure Rust of the C++ library of the same name by its original author. This work has been sponsored by Enlightware GmbH.

Usage

To use nabo in your project, you need to implement the nabo::Point trait for your point type. You can see an example in src/dummy_point which is available when nabo is compiled with the dummy_point feature (default). If you want to avoid a dependency to rand, disable the dummy_point feature.

Benchmark

You can benchmark nabo using the following command:

cargo bench
