Classes
struct	carla::multigpu::CommandHeader
struct	carla::multigpu::GetTokenRequest
	GET_TOKEN request payload. More...
struct	carla::multigpu::LoadMapExtras
	What a LOAD_MAP carries besides the map: for a world the primary generated from OpenDRIVE (generate_opendrive_world), the OpenDRIVE and the generation parameters (rpc::OpendriveGenerationParameters, msgpack). More...
struct	carla::multigpu::LoadMapRequest

Typedefs
using	carla::multigpu::load_map_id_type = uint32_t
	Identifies one LOAD_MAP broadcast.

Enumerations
enum	carla::multigpu::MultiGPUCommand : uint32_t {   carla::multigpu::SEND_FRAME = 0 , carla::multigpu::LOAD_MAP , carla::multigpu::GET_TOKEN , carla::multigpu::ENABLE_ROS ,   carla::multigpu::DISABLE_ROS , carla::multigpu::IS_ENABLED_ROS , carla::multigpu::YOU_ALIVE }

Functions
std::string	carla::multigpu::MakeEpisodeReadyMessage (load_map_id_type load_id)
	Episode-ready message: the marker followed by the load id of the LOAD_MAP that started the episode, so the primary can ignore a stale one.
std::string	carla::multigpu::MakeLoadMapPayload (std::string_view map, load_map_id_type load_id, const LoadMapExtras &extras={})
	LOAD_MAP payload: the NUL-terminated map path, the load id, then the extras as [u8 kind][u32 size][bytes] fields; a reader skips the kinds it does not know.
std::optional< load_map_id_type >	carla::multigpu::ParseEpisodeReadyMessage (std::string_view payload)
	Load id of an episode-ready message (0 for a bare marker), or nullopt if payload is not one.
LoadMapRequest	carla::multigpu::ParseLoadMapPayload (std::string_view payload)

Variables
constexpr std::string_view	carla::multigpu::kEpisodeReadyMarker {"EPISODE_READY"}
	Sent unprompted by a secondary, on the same channel as command responses, to signal that its episode is ready to receive frames (see Router::HandleResponse).
constexpr std::size_t	carla::multigpu::kMaxMultiGpuMessageBytes = (std::size_t{1u} << 30u) + (std::size_t{1u} << 20u)
	Largest message either end accepts: a frame (capped at 1 GiB by the primary) plus room for its headers.
constexpr std::string_view	carla::multigpu::kTokenNotReadyMarker {"TOKEN_NOT_READY"}
	GET_TOKEN reply when the secondary cannot resolve the sensor to a stream (or the request is malformed).
