Struct ResourceManager

pub struct ResourceManager { /* private fields */ }

ResourceManager

Convenient method for getting the path to the resources of the backends.

Backends

• maliput_malidrive: Resources from maliput_malidrive are brought by maliput-sdk package. All the maliput_malidrive resources are stored in the same directory: (See https://github.com/maliput/maliput_malidrive/tree/main/resources)

Example

How to get all the resources from the maliput_malidrive backend:

let resource_manager = maliput::ResourceManager::new();
let all_resources_in_malidrive = resource_manager.get_all_resources_by_backend("maliput_malidrive");

How to get the path to the TShapeRoad.xodr file from the maliput_malidrive backend:

let resource_manager = maliput::ResourceManager::new();
let t_shape_road_xodr_path = resource_manager.get_resource_path_by_name("maliput_malidrive", "TShapeRoad.xodr");
assert!(t_shape_road_xodr_path.is_some());
assert!(t_shape_road_xodr_path.unwrap().exists());
