Rust port of Google Maps Polyline Encoding

Description

Encode and decode polyines in Rust using this package.

Polyline encoding is a lossy compression algorithm that allows you to store a series of coordinates as a single string. Point coordinates are encoded using signed values.

Note

I have no affiliation with Google or Google Maps. This package was ported from https://github.com/googlemaps/js-polyline-codec.

Example

``rust use polyline_codec::LatLng; let encoded = "_p~iF~ps|U_ulLnnqC_mqNvxq@"; asserteq!( polylinecodec::decode(encoded, 5).unwrap(), vec![ LatLng(38.5, -120.2,), LatLng(40.7, -120.95,), LatLng(43.252, -126.453,), ] );

let path = &[(38.5, -120.2), (40.7, -120.95), (43.252, -126.453)];
assert_eq!(
    polyline_codec::encode(path, 5).unwrap(),
    "_p~iF~ps|U_ulLnnqC_mqNvxq`@",
);
