Enum google_maps::directions::request::unit_system::UnitSystem

pub enum UnitSystem {
    Imperial,
    Metric,
}

Specifies the unit system to use when displaying results.

Directions results contain text within distance fields that may be displayed to the user to indicate the distance of a particular “step” of the route. By default, this text uses the unit system of the origin’s country or region.

For example, a route from “Chicago, IL” to “Toronto, ONT” will display results in miles, while the reverse route will display results in kilometers. You may override this unit system by setting one explicitly within the request’s units parameter, passing one of the following values:

Note: this unit system setting only affects the text displayed within distance fields. The distance fields also contain values which are always expressed in meters.

Variants

Imperial

Specifies that distances in the response should be expressed in imperial units, miles and feet.

Metric

Specifies that distances in the response should be expressed in metric units, using kilometres and metres.
