Function get_controllers 

pub fn get_controllers() -> Controllers

Retrieve the controllers of the Satellite.

This function retrieves the list of controllers currently set for the application. A controller is represented as a key-value pair where the key is the ControllerId (a Principal) and the value is a Controller struct containing metadata and scope details about the controller.

Returns

• Controllers: A HashMap where:
  • The key is a ControllerId (type alias for Principal).
  • The value is a Controller struct that includes:
    • metadata: Additional metadata about the controller, such as name or description.
    • created_at: The timestamp when the controller was created.
    • updated_at: The timestamp when the controller was last updated.
    • expires_at: An optional timestamp indicating when the controller expires.
    • scope: The ControllerScope, which specifies the access level (Write or Admin).

Example

let controllers = get_controllers();
for (controller_id, controller) in controllers.iter() {
    println!("Controller ID: {}", controller_id);
    println!("Scope: {:?}", controller.scope);
    if let Some(expires_at) = controller.expires_at {
        println!("Expires at: {}", expires_at);
    }
}

This function is useful for checking the current permissions.
