type OracleSpec struct {

	SchemaVersion uint32 `toml:"schemaVersion"`

	models.OffchainReportingOracleSpec

	// The `Pipeline` field is only used during unmarshaling.  A pipeline.TaskDAG
	// is a type that implements gonum.org/v1/gonum/graph#Graph, which means that
	// you can dot.Unmarshal(...) raw DOT source directly into it, and it will
	// be a fully-instantiated DAG containing information about all of the nodes
	// and edges described by the DOT.  Our pipeline.TaskDAG type has a method
	// called `.TasksInDependencyOrder()` which converts this node/edge data
	// structure into task specs which can then be saved to the database.
	Pipeline pipeline.TaskDAG `toml:"observationSource"`
	// contains filtered or unexported fields
}

OracleSpec is a wrapper for `models.OffchainReportingOracleSpec`, the DB representation of the OCR job spec. It fulfills the job.Spec interface and has facilities for unmarshaling the pipeline DAG from the job spec text.
