Module transaction_extensions 

This module contains implementations for common transaction extensions, each of which implements TransactionExtension, and can be used in conjunction with AnyOf to configure the set of transaction extensions which are known about when interacting with a chain.

Structs

AnyOf

This accepts a tuple of TransactionExtensions, and will dynamically make use of whichever ones are actually required for the chain in the correct order, ignoring the rest. This is a sensible default, and allows for a single configuration to work across multiple chains.

ChargeAssetTxPayment

The ChargeAssetTxPayment transaction extension.

ChargeAssetTxPaymentParams

Parameters to configure the ChargeAssetTxPayment transaction extension.

ChargeTransactionPayment

The ChargeTransactionPayment transaction extension.

ChargeTransactionPaymentParams

Parameters to configure the ChargeTransactionPayment transaction extension.

CheckGenesis

The CheckGenesis transaction extension.

CheckMetadataHash

The CheckMetadataHash transaction extension.

CheckMortality

The CheckMortality transaction extension.

CheckMortalityParams

Parameters to configure the CheckMortality transaction extension.

CheckNonce

The CheckNonce transaction extension.

CheckNonceParams

Configure the nonce used.

CheckSpecVersion

The CheckSpecVersion transaction extension.

CheckTxVersion

The CheckTxVersion transaction extension.

VerifySignature

The VerifySignature extension. For V5 General transactions, this is how a signature is provided. The signature is constructed by signing a payload which contains the transaction call data as well as the encoded “additional” bytes for any extensions after this one in the list.

Enums

CheckMetadataHashMode

Is metadata checking enabled or disabled?

VerifySignatureDetails

This allows a signature to be provided to the VerifySignature transaction extension.

Traits

Params

The parameters (ie ExtrinsicParams::Params) can also have data injected into them, allowing Subxt to retrieve data from the chain and amend the parameters with it when online.

TransactionExtension

A single TransactionExtension has a unique name, but is otherwise the same as ExtrinsicParams in describing how to encode the extra and additional data.
