pub struct CurrencyAdapter<C, OU>(/* private fields */);
👎Deprecated: Please use the fungible trait and FungibleAdapter. This struct will be removed some time after March 2024.
Expand description
Implements the transaction payment for a pallet implementing the Currency
trait (eg. the pallet_balances) using an unbalance handler (implementing
OnUnbalanced
).
The unbalance handler is given 2 unbalanceds in OnUnbalanced::on_unbalanceds
: fee
and
then tip
.

Default implementation for a Currency and an OnUnbalanced handler.
The unbalance handler is given 2 unbalanceds in OnUnbalanced::on_unbalanceds
: fee
and
then tip
.

fn withdraw_fee( who: &T::AccountId, _call: &T::RuntimeCall, _info: &DispatchInfoOf<T::RuntimeCall>, 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
.

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 corrected_fee
already includes the tip
.
