Classes
struct	pulp::dataplane::ValueChannelInfo
	What a channel is, for discovery and for a UI lint to check names against. More...
struct	pulp::dataplane::ValueChannelTelemetrySnapshot
	A coherent continuous payload copied by the existing UI reader path. More...
struct	pulp::dataplane::ValueChannelTelemetryEventBatch
	One producer event batch retained by the ordered telemetry tap. More...
struct	pulp::dataplane::ValueChannelTelemetryEventStats
	Current producer-tap state. Overflow is cumulative for the source lifetime. More...
struct	pulp::dataplane::ValueChannelTelemetryDescriptor
	Stable metadata for a channel held by a telemetry attachment. More...
class	pulp::dataplane::ValueChannelTelemetryAttachment
	Exclusive reader attachment for every telemetry sidecar in one channel set. More...

Enumerations
enum class	pulp::dataplane::ValueChannelShape { pulp::dataplane::scalar , pulp::dataplane::meter , pulp::dataplane::vector , pulp::dataplane::events }
