func ExtractRawBytes added in v1.11.0

func ExtractRawBytes(input []byte) ([]byte, error)

Process result from the EA saved by a jsonparse pipeline task. That value is a valid JSON string so it contains double quote characters. Allowed inputs are:

  1. "" (2 characters) -> return empty byte array
  2. "0x<val>" where <val> is a non-empty, valid hex -> return hex-decoded <val>

type RequestState

type RequestState int8
const (
	// IN_PROGRESS is the initial state of a request, set right after receiving it in an on-chain event.
	IN_PROGRESS RequestState = iota

	// RESULT_READY means that computation has finished executing (with either success or error).
	// OCR2 reporting includes only requests in RESULT_READY state (for Query and Observation phases).
	RESULT_READY

	// TIMED_OUT request has been waiting to get confirmed on chain for too long.
	// It won't be included in OCR2 reporting rounds any more.
	TIMED_OUT

	// FINALIZED request is a part of a report produced by OCR2 and has now entered the transmission protocol
	// (i.e. passed through ShouldAcceptFinalizedReport()).
	FINALIZED

	// CONFIRMED state indicates that we received an on-chain confirmation event
	// (with or without this node's participation in an earlier OCR round).
	// We can transition here at any time (full fan-in) and cannot transition out (empty fan-out).
	// This is a desired and expected final state for every request.
	CONFIRMED
