Classes
struct	mm::node::DeviceStateInfo
	Current AL state snapshot for a single device. More...
struct	mm::node::ProcessImageObjectInfo
	One mapped object in the published process image, with its name resolved. More...
struct	mm::node::ProcessImageInfo
	API-facing snapshot of the currently published process image and its runtime health. More...
struct	mm::node::OutputStageRequest
	One object to stage into the output process image, as parsed from a batch write request. More...
struct	mm::node::OutputStageResult
	Per-object outcome of a batch output stage. More...
struct	mm::node::SlaveConfigInfo
	A slave's static ESC configuration plus its resolved device name. More...
struct	mm::node::DeviceDiagnosticsInfo
	A slave's live ESC health diagnostics plus its resolved device name. More...
struct	mm::node::DcSyncInfo
	A slave's live distributed-clock sync status plus its resolved device name. More...
struct	mm::node::DeviceManagerConfig
	Runtime tuning passed to DeviceManager::init. Every field has a sensible default, so a caller can pass {} (or omit it) and override only what it cares about; new knobs can be added here without changing the init signature. More...
class	mm::node::DeviceManager
	Owns the fieldbus driver and node collection, and drives PDO exchange. More...
struct	mm::node::DeviceManager::PdoSampleSpec
	Everything needed to decode one PDO object from a raw process-image snapshot: which image it lives in, where, and how wide / what type. More...
