func (*AtomicTransactionComposer) Execute 

func (atc *AtomicTransactionComposer) Execute(client *algod.Client, ctx context.Context, waitRounds uint64) (ExecuteResult, error)

Execute sends the transaction group to the network and waits until it's committed to a block. An error will be thrown if submission or execution fails.

The composer's status must be SUBMITTED or lower before calling this method, since execution is only allowed once. If submission is successful, this composer's status will update to SUBMITTED. If the execution is also successful, this composer's status will update to COMMITTED.

func (*DryrunTxnResult) AppCallRejected 

func (d *DryrunTxnResult) AppCallRejected() bool

AppCallRejected returns true if the Application Call was rejected for this transaction

func (*DryrunTxnResult) GetAppCallTrace 

func (d *DryrunTxnResult) GetAppCallTrace(spc StackPrinterConfig) string

GetAppCallTrace returns a string representing a stack trace for this transactions application logic evaluation

LogicSigRejected returns true if the LogicSig was rejected for this transaction

type EmptyTransactionSigner added in v2.3.0 

type EmptyTransactionSigner struct{}

EmptyTransactionSigner is a TransactionSigner that produces signed transaction objects without signatures. This is useful for simulating transactions, but it won't work for actual submission.

func (EmptyTransactionSigner) Equals added in v2.3.0 

func (txSigner EmptyTransactionSigner) Equals(other TransactionSigner) bool

Equals returns true if the other TransactionSigner equals this one.

func (EmptyTransactionSigner) SignTransactions added in v2.3.0 

func (txSigner EmptyTransactionSigner) SignTransactions(txGroup []types.Transaction, indexesToSign []int) ([][]byte, error)

SignTransactions returns SignedTxn bytes but does not sign them.

type ExecuteResult 

type ExecuteResult struct {
	// The round in which the executed transaction group was confirmed on chain
	ConfirmedRound uint64
	// A list of the TxIDs for each transaction in the executed group
	TxIDs []string
	// For each ABI method call in the executed group (created by the AddMethodCall method), this
	// slice contains information about the method call's return value
	MethodResults []ABIMethodResult
}

ExecuteResult contains the results of successfully calling the Execute method on an AtomicTransactionComposer object.

type LogicSigAccountTransactionSigner 

type LogicSigAccountTransactionSigner struct {
	LogicSigAccount crypto.LogicSigAccount
}

LogicSigAccountTransactionSigner is a TransactionSigner that can sign transactions for the provided LogicSigAccount.

func (LogicSigAccountTransactionSigner) Equals 

func (txSigner LogicSigAccountTransactionSigner) Equals(other TransactionSigner) bool

Equals returns true if the other TransactionSigner equals this one.

func (LogicSigAccountTransactionSigner) SignTransactions 

func (txSigner LogicSigAccountTransactionSigner) SignTransactions(txGroup []types.Transaction, indexesToSign []int) ([][]byte, error)

SignTransactions signs the provided transactions with the private key of the account.

type MultiSigAccountTransactionSigner 

type MultiSigAccountTransactionSigner struct {
	Msig crypto.MultisigAccount
	Sks  [][]byte
}

MultiSigAccountTransactionSigner is a TransactionSigner that can sign transactions for the provided MultiSig Account

func (MultiSigAccountTransactionSigner) Equals 

func (txSigner MultiSigAccountTransactionSigner) Equals(other TransactionSigner) bool

Equals returns true if the other TransactionSigner equals this one.

func (MultiSigAccountTransactionSigner) SignTransactions 

func (txSigner MultiSigAccountTransactionSigner) SignTransactions(txGroup []types.Transaction, indexesToSign []int) ([][]byte, error)

SignTransactions signs the provided transactions with the private keys of the account.

type SimulateResult added in v2.3.0 

type SimulateResult struct {
	// The result of the transaction group simulation
	SimulateResponse models.SimulateResponse
	// For each ABI method call in the executed group (created by the AddMethodCall method), this
	// slice contains information about the method call's return value
	MethodResults []ABIMethodResult
}

SimulateResult contains the results of calling the Simulate method on an AtomicTransactionComposer object.

type StackPrinterConfig 

type StackPrinterConfig struct {
	MaxValueWidth   int  // Set the max width of the column, 0 is no max
	TopOfStackFirst bool // Set the order of the stack values printed, true is top of stack (last pushed) first
}

StackPrinterConfig holds some configuration parameters for how to print a DryrunResponse stack trace

func DefaultStackPrinterConfig 

func DefaultStackPrinterConfig() StackPrinterConfig

DefaultStackPrinterConfig returns a new StackPrinterConfig with reasonable defaults

type TransactionSigner 

type TransactionSigner interface {
	SignTransactions(txGroup []types.Transaction, indexesToSign []int) ([][]byte, error)
	Equals(other TransactionSigner) bool
}

TransactionSigner represents a function which can sign transactions from an atomic transaction group. @param txnGroup - The atomic group containing transactions to be signed @param indexesToSign - An array of indexes in the atomic transaction group that should be signed @returns An array of encoded signed transactions. The length of the 

array will be the same as the length of indexesToSign, and each index i in the array
corresponds to the signed transaction from txnGroup[indexesToSign[i]]

type TransactionWithSigner 

type TransactionWithSigner struct {
	// An unsigned transaction
	Txn types.Transaction
	// A transaction signer that can authorize the transaction
	Signer TransactionSigner
}

TransactionWithSigner represents an unsigned transactions and a signer that can authorize that transaction.
