Constants ¶
const ( BlockchainEmpty = "blockchain identifier has empty blockchain field" NetworkEmpty = "blockchain identifier has empty network field" BlockNotFull = "block identifier needs both fields filled for this request" BlockLength = "block identifier has invalid hash field length" AddressEmpty = "account identifier has empty address field" AddressLength = "account identifier has invalid address field length" CurrenciesEmpty = "currency identifier list is empty" SymbolEmpty = "currency identifier has empty symbol field" TxHashEmpty = "transaction identifier has empty hash field" TxLength = "transaction identifier has invalid hash filed length" TxInvalidOps = "transaction operations are invalid" TxBodyEmpty = "transaction text is empty" SignaturesEmpty = "signature list is empty" )
const ( HexIDSize = 2 * len(flow.ZeroID) HexAddressSize = 2 * flow.AddressLength )
Sizes are multiplied by two because hex-encoded strings use two characters for every byte.
Variables ¶
var ( ErrBlockLength = errors.New(BlockLength) ErrBlockIncomplete = errors.New(BlockNotFull) ErrAddressLength = errors.New(AddressLength) ErrTxLength = errors.New(TxLength) )
