Functions

func ToLoadReport

func ToLoadReport(md metadata.MD) (*v3orcapb.OrcaLoadReport, error)

ToLoadReport unmarshals a binary encoded [ORCA LoadReport] protobuf message from md and returns the corresponding struct. The load report is expected to be stored as the value for key "endpoint-load-metrics-bin".

If no load report was found in the provided metadata, if multiple load reports are found, or if the load report found cannot be parsed, an error is returned.
