Struct ChargeFrqTransactionPayment

pub struct ChargeFrqTransactionPayment<T: Config>(/* private fields */);

Require the transactor pay for themselves and maybe include a tip to gain additional priority in the queue.

Transaction Validity

This extension sets the priority field of TransactionValidity depending on the amount of tip being paid per weight unit.

Operational transactions will receive an additional priority bump, so that they are normally considered before regular transactions.

👎Deprecated: Use TransactionExtension instead.

Construct any additional data that should be in the signed payload of the transaction. Can also perform any pre-signature-verification checks and return an error if needed.

fn validate( &self, who: &Self::AccountId, call: &Self::Call, info: &DispatchInfoOf<Self::Call>, len: usize, ) -> TransactionValidity

👎Deprecated: Use TransactionExtension instead.

👎Deprecated: Use TransactionExtension instead.

Do any pre-flight stuff for a signed transaction.
