Required Methods§

source

fn extract_signer( xt: <<T as Config>::Block as BlockT>::Extrinsic, ) -> (Option<<T as Config>::AccountId>, DispatchInfo)

Extracts signer from given extrinsic and its dispatch info.

source

fn on_storage_fees_charged( charged_fees: <<T as Config>::Currency as Inspect<<T as Config>::AccountId>>::Balance, tx_size: u32, ) -> Result<(), TransactionValidityError>

Hook to note operator rewards for charged storage fees.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
