Struct pallet_transaction_payment::CurrencyAdapter [−][src]
Implements the transaction payment for a module implementing the Currency
trait (eg. the pallet_balances) using an unbalance handler (implementing
OnUnbalanced
).

OU: OnUnbalanced<<C as Currency<<T as Config>::AccountId>>::NegativeImbalance>,
Default implementation for a Currency and an OnUnbalanced handler.
type LiquidityInfo = Option<<C as Currency<<T as Config>::AccountId>>::NegativeImbalance>
type Balance = <C as Currency<<T as Config>::AccountId>>::Balance
The underlying integer type in which fees are calculated.
fn withdraw_fee(
who: &T::AccountId,
_call: &T::Call,
_info: &DispatchInfoOf<T::Call>,
fee: Self::Balance,
tip: Self::Balance
) -> Result<Self::LiquidityInfo, TransactionValidityError>

who: &T::AccountId,
_call: &T::Call,
_info: &DispatchInfoOf<T::Call>,
fee: Self::Balance,
tip: Self::Balance
) -> Result<Self::LiquidityInfo, TransactionValidityError>
Withdraw the predicted fee from the transaction origin.
Note: The fee
already includes the tip
.

who: &T::AccountId,
_dispatch_info: &DispatchInfoOf<T::Call>,
_post_info: &PostDispatchInfoOf<T::Call>,

[src]
who: &T::AccountId,
_dispatch_info: &DispatchInfoOf<T::Call>,
_post_info: &PostDispatchInfoOf<T::Call>,
corrected_fee: Self::Balance,
tip: Self::Balance,
already_withdrawn: Self::LiquidityInfo
) -> Result<(), TransactionValidityError>
Hand the fee and the tip over to the [OnUnbalanced]
implementation.
Since the predicted fee might have been too high, parts of the fee may
be refunded.
Note: The fee
already includes the tip
.
