Types ¶
type Intent ¶
type Intent struct {
From flow.Address
To flow.Address
Amount cadence.UFix64
Payer flow.Address
Proposer flow.Address
}
Intent describes the intent of an array of Rosetta operations.
type Submitter ¶
type Submitter interface {
Transaction(tx *sdk.Transaction) error
}
type Transactor ¶
type Transactor struct {
// contains filtered or unexported fields
}
Transactor can determine the transaction intent from an array of Rosetta operations, create a Flow transaction from a transaction intent and translate a Flow transaction back to an array of Rosetta operations.
func New ¶
func New(validate Validator, generate Generator, invoke Invoker, submit Submitter) *Transactor
New creates a new transactor to handle interactions with Flow transactions.
func (*Transactor) AttachSignatures ¶
func (t *Transactor) AttachSignatures(unsigned string, signatures []object.Signature) (string, error)
AttachSignatures adds the given signatures to the transaction.
func (*Transactor) CompileTransaction ¶
func (t *Transactor) CompileTransaction(rosBlockID identifier.Block, intent *Intent, sequence uint64) (string, error)
CompileTransaction creates a complete Flow transaction from the given intent and metadata.
func (*Transactor) DeriveIntent ¶
func (t *Transactor) DeriveIntent(operations []object.Operation) (*Intent, error)
DeriveIntent derives a transaction Intent from two operations given as input. Specified operations should be symmetrical, a deposit and a withdrawal from two different accounts. At the moment, the only fields taken into account are the account IDs, amounts and type of operation.
func (*Transactor) HashPayload ¶
func (t *Transactor) HashPayload(rosBlockID identifier.Block, unsigned string, signer identifier.Account) (string, string, error)
func (*Transactor) ParseTransaction ¶
func (t *Transactor) ParseTransaction(payload string) (identifier.Block, uint64, []object.Operation, []identifier.Account, error)
ParseTransactions processes the flow transaction, validates its correctness and translates it to a list of operations and a list of signers. TODO: Refactor this function, probably into several smaller function with a small amount of return values: => https://github.com/optakt/flow-dps/issues/392
func (*Transactor) SubmitTransaction ¶
func (t *Transactor) SubmitTransaction(signed string) (identifier.Transaction, error)
func (*Transactor) TransactionIdentifier ¶
func (t *Transactor) TransactionIdentifier(signed string) (identifier.Transaction, error)
type Validator ¶
type Validator interface {
Account(rosAccountID identifier.Account) (address flow.Address, err error)
Block(rosBlockID identifier.Block) (height uint64, blockID flow.Identifier, err error)
Currency(currency identifier.Currency) (symbol string, decimals uint, err error)
}
