Types

type Module

type Module struct {
	// contains filtered or unexported fields
}

Module implements the TransactionPaymentApi Runtime API definition.

For more information about API definition, see: https://spec.polkadot.network/chap-runtime-api#sect-runtime-transactionpaymentapi-module

func New

func New(decoder types.RuntimeDecoder, txPayments transaction_payment.Module, logger log.RuntimeLogger) Module

func (Module) Item

func (m Module) Item() primitives.ApiItem

Item returns the first 8 bytes of the Blake2b hash of the name and version of the api module.

func (Module) Metadata

func (m Module) Metadata() primitives.RuntimeApiMetadata

Metadata returns the runtime api metadata of the module.

func (Module) Name

func (m Module) Name() string

Name returns the name of the api module.

func (Module) QueryFeeDetails

func (m Module) QueryFeeDetails(dataPtr int32, dataLen int32) int64

QueryFeeDetails queries the detailed fee of an extrinsic. It takes two arguments: - dataPtr: Pointer to the data in the Wasm memory. - dataLen: Length of the data. which represent the SCALE-encoded extrinsic and its length. Returns a pointer-size of the SCALE-encoded detailed fee.

For more information about function definition, see: https://spec.polkadot.network/chap-runtime-api#sect-rte-transactionpaymentapi-query-fee-details

func (Module) QueryInfo

func (m Module) QueryInfo(dataPtr int32, dataLen int32) int64

QueryInfo queries the data of an extrinsic. It takes two arguments: - dataPtr: Pointer to the data in the Wasm memory. - dataLen: Length of the data. which represent the SCALE-encoded extrinsic and its length. Returns a pointer-size of the SCALE-encoded weight, dispatch class and partial fee.
