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.
