Module polkadot_sdk_frame::traits::transaction_extension

The transaction extension trait.

Structs

• AsTransactionExtensionDeprecated
  Adapter to use a SignedExtension in the place of a TransactionExtension.
• PhantomData
  Zero-sized type used to mark things that “act like” they own a T.
• TransactionExtensionMetadata
  Information about a TransactionExtension for the runtime metadata.

Traits

• 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.
• 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

• ValidateResult
  Shortcut for the result value of the validate function.
