Overview

Package tocpb provides protobuf bindings and conversion between proto wire types and the canonical Go types in toc/core.

Conversion functions bridge the proto presence model (optional fields) and the Go presence model (ObservationMask bitmask, HasIdleRatio/HasBlockedRatio bools).

FromProto functions return (T, error) and validate invariants. ToProto functions are infallible — the Go types are assumed valid.

type ObservationBatch

	PipelineId         string              `protobuf:"bytes,1,opt,name=pipeline_id,json=pipelineId,proto3" json:"pipeline_id,omitempty"`
	TimestampUnixNano  int64               `protobuf:"varint,2,opt,name=timestamp_unix_nano,json=timestampUnixNano,proto3" json:"timestamp_unix_nano,omitempty"`    // window end, UTC nanoseconds

	Observations       []*StageObservation `protobuf:"bytes,4,rep,name=observations,proto3" json:"observations,omitempty"`
	// contains filtered or unexported fields
}

ObservationBatch wraps a set of observations for one analysis window. This is the wire message for NATS transport.

All observations in a batch MUST refer to the same analysis window. The batch is produced by a single aggregator — there is no cross-host assembly. Stage names MUST be unique within a batch.

timestamp_unix_nano is the window end time (when the aggregator sampled). window_duration_nano is the length of the analysis window. Together they define [end - duration, end).

BatchToProto converts a slice of core.StageObservation values to a proto ObservationBatch with the given metadata.

StageDiagnosis holds the classification for one stage. Contains ratios and counts, NOT rates. The caller converts to rates using their own time model (wall-clock or ticks).

type StageObservation 

type StageObservation struct {
	Stage string `protobuf:"bytes,1,opt,name=stage,proto3" json:"stage,omitempty"`
	// Work accounting (abstract units — nanoseconds or ticks).

	// Optional work accounting — absent means not observed.

	BlockedWork *uint64 `protobuf:"varint,5,opt,name=blocked_work,json=blockedWork,proto3,oneof" json:"blocked_work,omitempty"`
	// Item counters over the window.

	Workers    int32  `protobuf:"varint,10,opt,name=workers,proto3" json:"workers,omitempty"`
	// contains filtered or unexported fields
}

StageObservation is the canonical input to the analyzer. One per stage per analysis window.

Invariant: busy_work + idle_work + blocked_work <= capacity_work. Failures is a subset of completions. Adapters should aim for equality in the work invariant; the analyzer tolerates inequality.

Presence: idle_work, blocked_work, completions, failures, and queue_depth are optional — not all adapters can observe them. Non-optional scalars (busy_work, capacity_work, arrivals, workers) use proto3 default zero when absent. Converters validate semantics (e.g., stage name non-empty, counts non-negative).

func ObservationToProto 

func ObservationToProto(o core.StageObservation) *StageObservation

ObservationToProto converts a core.StageObservation to its proto form. Optional fields are set only when the corresponding mask bit is present.
