Type will return PreRuntimeDigestType

type SealDigest 

type SealDigest struct {
	ConsensusEngineID ConsensusEngineID
	Data              []byte
}

SealDigest contains the seal or signature. This is only used by native code.

func (*SealDigest) Decode 

func (d *SealDigest) Decode(r io.Reader) error

Decode will decode into SealDigest ConsensusEngineID and Data

func (*SealDigest) Encode 

func (d *SealDigest) Encode() ([]byte, error)

Type will return SealDigest type

type SystemInfo 

type SystemInfo struct {
	SystemName    string
	SystemVersion string
}

SystemInfo struct to hold system related information

type TransactionSource added in v0.3.0 

type TransactionSource uint8

TransactionSource represents source of Transaction 

const (
	// TxnInBlock indicates transaction is already included in block.
	//
	// This means that we can't really tell where the transaction is coming from,
	// since it's already in the received block. Note that the custom validation logic
	// using either `Local` or `External` should most likely just allow `InBlock`
	// transactions as well.
	TxnInBlock TransactionSource = iota

	// TxnLocal indicates transaction is coming from a local source.
	//
	// This means that the transaction was produced internally by the node
	// (for instance an Off-Chain Worker, or an Off-Chain Call), as opposed
	// to being received over the network.
	TxnLocal

	// TxnExternal indicates transaction has been received externally.
	//
	// This means the transaction has been received from (usually) "untrusted" source,
	// for instance received over the network or RPC.
	TxnExternal
)
