A trait that exposes all the transaction payment details to pallet_revive.

This trait is sealed. Use Info.

Provided Methods

fn integrity_test()

Check that the fee configuration of the chain is valid.

This is being called by the pallets integrity_check.

fn next_fee_multiplier() -> FixedU128

Exposes the current fee multiplier of the chain.

fn next_fee_multiplier_reciprocal() -> FixedU128

The reciprocal of the next fee multiplier.

Needed when dividing a fee by the multiplier before presenting it to the eth wallet as gas. Needed because the wallet will multiply it with the gas_price which includes this multiplicator.

fn tx_fee(_len: u32, _call: &<T as Config>::RuntimeCall) -> BalanceOf<T>

Calculate the fee of a transaction including the next fee multiplier adjustment.

fn tx_fee_from_weight(_encoded_len: u32, _weight: &Weight) -> BalanceOf<T>

Calculate the fee using the weight instead of a dispatch info.

fn fixed_fee(_encoded_len: u32) -> BalanceOf<T>

The base extrinsic and len fee.

fn ensure_not_overdrawn( _fee: BalanceOf<T>, result: DispatchResultWithPostInfo, ) -> DispatchResultWithPostInfo

Makes sure that not too much storage deposit was withdrawn.

fn dispatch_info(_call: &<T as Config>::RuntimeCall) -> DispatchInfo

Get the dispatch info of a call with the proper extension weight set.

fn base_dispatch_info(_call: &mut <T as Config>::RuntimeCall) -> DispatchInfo

The dispatch info with the weight argument set to 0.

fn encoded_len(_eth_transact_call: <T as Config>::RuntimeCall) -> u32

Calculate the encoded length of a call.

fn weight_to_fee(_weight: &Weight) -> BalanceOf<T>

Convert a weight to an unadjusted fee.

fn weight_to_fee_average(_weight: &Weight) -> BalanceOf<T>

Convert a weight to an unadjusted fee using an average instead of maximum.

fn fee_to_weight(_fee: BalanceOf<T>) -> Weight

Convert an unadjusted fee back to a weight.

fn length_to_fee(_len: u32) -> BalanceOf<T>

Convert the length of a transaction to an unadjusted weight.

fn deposit_txfee( _credit: Credit<<T as Config>::AccountId, <T as Config>::Currency>, )

Add some additional fee to the pallet_transaction_payment credit.

fn withdraw_txfee( _amount: BalanceOf<T>, ) -> Option<Credit<<T as Config>::AccountId, <T as Config>::Currency>>

Withdraw some fee to pay for storage deposits.

fn remaining_txfee() -> BalanceOf<T>

Return the remaining transaction fee.

fn compute_actual_fee( _encoded_len: u32, _info: &DispatchInfo, _result: &DispatchResultWithPostInfo, ) -> BalanceOf<T>

Compute the actual post_dispatch fee

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.
