Types

type TestTx

type TestTx struct {
	choices.TestDecidable

	DependenciesV    []Tx

TestTx is a useful test tx

func (*TestTx) Bytes

func (t *TestTx) Bytes() []byte

func (*TestTx) Dependencies

func (t *TestTx) Dependencies() ([]Tx, error)

func (*TestTx) InputIDs

func (t *TestTx) InputIDs() []ids.ID

func (*TestTx) Verify

func (t *TestTx) Verify(context.Context) error

type Tx

type Tx interface {
	choices.Decidable

	// Dependencies is a list of transactions upon which this transaction
	// depends. Each element of Dependencies must be verified before Verify is
	// called on this transaction.
	//
	// Similarly, each element of Dependencies must be accepted before this
	// transaction is accepted.
	Dependencies() ([]Tx, error)

	// InputIDs is a set where each element is the ID of a piece of state that
	// will be consumed if this transaction is accepted.
	//
	// In the context of a UTXO-based payments system, for example, this would
	// be the IDs of the UTXOs consumed by this transaction
	InputIDs() []ids.ID

	// Verify that the state transition this transaction would make if it were
	// accepted is valid. If the state transition is invalid, a non-nil error
	// should be returned.
	//
	// It is guaranteed that when Verify is called, all the dependencies of
	// this transaction have already been successfully verified.
	Verify(context.Context) error

	// Bytes returns the binary representation of this transaction.
	//
	// This is used for sending transactions to peers. Another node should be
	// able to parse these bytes to the same transaction.
	Bytes() []byte
}

Tx consumes state.
