Module transaction

This is already part of the prelude.

Macros

impl_tx_ext_default

Helper macro to be used in a impl TransactionExtension block to add default implementations of weight, validate, prepare or any combinations of the them.

Structs

CallMetadata

The function and pallet name of the Call.

ValidTransaction

Information concerning a valid transaction.

Enums

InvalidTransaction

An invalid transaction validity.

Traits

AsTransactionAuthorizedOrigin

Interface to differentiate between Runtime Origins authorized to include a transaction into the block and dispatch it, and those who aren’t.

DispatchTransaction

Single-function utility trait with a blanket impl over TransactionExtension in order to provide transaction dispatching functionality. We avoid implementing this directly on the trait since we never want it to be overriden by the trait implementation.

GetCallMetadata

Gets the metadata for the Call - function name and pallet name.

TransactionExtension

Means by which a transaction may be extended. This type embodies both the data and the logic that should be additionally associated with the transaction. It should be plain old data.

Type Aliases

ExtensionVersion

Type to represent the version of the Extension used in this extrinsic.

ValidateResult

Shortcut for the result value of the validate function.
