Expand description

Encodes an array of coordinates into a polyline string

§Arguments

  • path - Array of coordinate pairs
  • precision - The precision factor (default: 5)

§Examples

use toolbox_rs::polyline::encode;

let path = vec![[38.5, -120.2], [40.7, -120.95], [43.252, -126.453]];
let encoded = encode(&path, 5);
assert_eq!(std::str::from_utf8(&encoded).unwrap(), "_p~iF~ps|U_ulLnnqC_mqNvxq`@");
