Types

type State

type State interface {
	djtx.UTXOState
	djtx.StatusState
	djtx.SingletonState
	TxState
}

State persistently maintains a set of UTXOs, transaction, statuses, and singletons.

func New

func New(db database.Database, parser txs.Parser, metrics prometheus.Registerer) (State, error)

type TxState

type TxState interface {
	// Tx attempts to load a transaction from storage.
	GetTx(txID ids.ID) (*txs.Tx, error)

	// PutTx saves the provided transaction to storage.
	PutTx(txID ids.ID, tx *txs.Tx) error

	// DeleteTx removes the provided transaction from storage.
	DeleteTx(txID ids.ID) error
}

TxState is a thin wrapper around a database to provide, caching, serialization, and de-serialization of transactions.

func NewTxState

func NewTxState(db database.Database, parser txs.Parser, metrics prometheus.Registerer) (TxState, error)
