#[copper_runtime]Expand description
Adds #[copper_runtime(config = "path", subsystem = "id", sim_mode = false/true, ignore_resources = false/true)]
to your application struct to generate the runtime.
if sim_mode is omitted, it is set to false.
if ignore_resources is omitted, it is set to false.
if subsystem is provided, config must point to a strict multi-Copper config and the
selected subsystem local config will be embedded into the generated runtime.
This will add a “runtime” field to your struct and implement the “new” and “run” methods.
