Functions

func CalculateGas

func CalculateGas(
	queryFunc func(string, []byte) ([]byte, int64, error), cdc *codec.Codec,
	txBytes []byte, adjustment float64,
) (estimate, adjusted uint64, err error)

CalculateGas simulates the execution of a transaction and returns both the estimate obtained by the query and the adjusted amount.

func CompleteAndBroadcastTxCLI

func CompleteAndBroadcastTxCLI(txBldr authtypes.TxBuilder, cliCtx context.CLIContext, msgs []sdk.Msg) error

CompleteAndBroadcastTxCLI implements a utility function that facilitates sending a series of messages in a signed transaction given a TxBuilder and a QueryContext. It ensures that the account exists, has a proper number and sequence set. In addition, it builds and signs a transaction with the supplied messages. Finally, it broadcasts the signed transaction to a node.

func EnrichWithGas

func EnrichWithGas(txBldr authtypes.TxBuilder, cliCtx context.CLIContext, msgs []sdk.Msg) (authtypes.TxBuilder, error)

EnrichWithGas calculates the gas estimate that would be consumed by the transaction and set the transaction's respective value accordingly.

func GenerateOrBroadcastMsgs

func GenerateOrBroadcastMsgs(cliCtx context.CLIContext, txBldr authtypes.TxBuilder, msgs []sdk.Msg) error

GenerateOrBroadcastMsgs creates a StdTx given a series of messages. If the provided context has generate-only enabled, the tx will only be printed to STDOUT in a fully offline manner. Otherwise, the tx will be signed and broadcasted.

func GetTxEncoder

func GetTxEncoder(cdc *codec.Codec) (encoder sdk.TxEncoder)

GetTxEncoder return tx encoder from global sdk configuration if ones is defined. Otherwise returns encoder with default logic.

func PrepareTxBuilder

func PrepareTxBuilder(txBldr authtypes.TxBuilder, cliCtx context.CLIContext) (authtypes.TxBuilder, error)

PrepareTxBuilder populates a TxBuilder in preparation for the build of a Tx.

func PrintUnsignedStdTx

func PrintUnsignedStdTx(txBldr authtypes.TxBuilder, cliCtx context.CLIContext, msgs []sdk.Msg) error

PrintUnsignedStdTx builds an unsigned StdTx and prints it to os.Stdout.

func QueryTx

func QueryTx(cliCtx context.CLIContext, hashHexStr string) (sdk.TxResponse, error)

QueryTx queries for a single transaction by a hash string in hex format. An error is returned if the transaction does not exist or cannot be queried.

func QueryTxsByEvents

func QueryTxsByEvents(cliCtx context.CLIContext, events []string, page, limit int) (*sdk.SearchTxsResult, error)

QueryTxsByEvents performs a search for transactions for a given set of events via the Aphelion RPC. An event takes the form of: "{eventAttribute}.{attributeKey} = '{attributeValue}'". Each event is concatenated with an 'AND' operand. It returns a slice of Info object containing txs and metadata. An error is returned if the query fails.

func ReadStdTxFromFile

func ReadStdTxFromFile(cdc *codec.Codec, filename string) (stdTx authtypes.StdTx, err error)

Read and decode a StdTx from the given filename. Can pass "-" to read from stdin.

func SignStdTx

func SignStdTx(
	txBldr authtypes.TxBuilder, cliCtx context.CLIContext, name string,
	stdTx authtypes.StdTx, appendSig bool, offline bool,
) (authtypes.StdTx, error)

SignStdTx appends a signature to a StdTx and returns a copy of it. If appendSig is false, it replaces the signatures already attached with the new signature. Don't perform online validation or lookups if offline is true.

func SignStdTxWithSignerAddress

func SignStdTxWithSignerAddress(txBldr authtypes.TxBuilder, cliCtx context.CLIContext,
	addr sdk.AccAddress, name string, stdTx authtypes.StdTx,
	offline bool) (signedStdTx authtypes.StdTx, err error)

SignStdTxWithSignerAddress attaches a signature to a StdTx and returns a copy of a it. Don't perform online validation or lookups if offline is true, else populate account and sequence numbers from a foreign account.

func ValidateTxResult

func ValidateTxResult(cliCtx context.CLIContext, resTx *ctypes.ResultTx) error

ValidateTxResult performs transaction verification.

func WriteGenerateStdTxResponse

func WriteGenerateStdTxResponse(w http.ResponseWriter, cliCtx context.CLIContext, br rest.BaseReq, msgs []sdk.Msg)

WriteGenerateStdTxResponse writes response for the generate only mode.

Types

type GasEstimateResponse

type GasEstimateResponse struct {
	GasEstimate uint64 `json:"gas_estimate" yaml:"gas_estimate"`
}

GasEstimateResponse defines a response definition for tx gas estimation.

func (GasEstimateResponse) String

func (gr GasEstimateResponse) String() string
