Encoding example

func ExampleEncodeCoords() {
    coords := [][]float64{
        {38.5, -120.2},
        {40.7, -120.95},
        {43.252, -126.453},
    }
    fmt.Println(string(polyline.EncodeCoords(coords)))
    // Output: _p~iF~ps|U_ulLnnqC_mqNvxq`@
}

Decoding example

func ExampleDecodeCoords() {
    buf := []byte("_p~iF~ps|U_ulLnnqC_mqNvxq`@")
    coords, _, _ := polyline.DecodeCoords(buf)
    fmt.Println(coords)
    // Output: [[38.5 -120.2] [40.7 -120.95] [43.252 -126.453]]
