Struct pallet_asset_tx_payment::FungiblesAdapter

pub struct FungiblesAdapter<CON, HC>(_);

Implements the asset transaction for a balance to asset converter (implementing ConversionToAssetBalance) and a credit handler (implementing HandleCredit).

The credit handler is given the complete fee in terms of the asset used for the transaction.

Trait Implementations

impl<T, CON, HC> OnChargeAssetTransaction<T> for FungiblesAdapter<CON, HC>where T: Config, CON: ConversionToAssetBalance<<<T as Config>::OnChargeTransaction as OnChargeTransaction<T>>::Balance, <<T as Config>::Fungibles as Inspect<<T as Config>::AccountId>>::AssetId, <<T as Config>::Fungibles as Inspect<<T as Config>::AccountId>>::Balance>, HC: HandleCredit<T::AccountId, T::Fungibles>, <<T as Config>::Fungibles as Inspect<<T as Config>::AccountId>>::AssetId: FullCodec + Copy + MaybeSerializeDeserialize + Debug + Default + Eq + TypeInfo,

Default implementation for a runtime instantiating this pallet, a balance to asset converter and a credit handler.

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

fn correct_and_deposit_fee( who: &T::AccountId, _dispatch_info: &DispatchInfoOf<T::RuntimeCall>, _post_info: &PostDispatchInfoOf<T::RuntimeCall>, corrected_fee: Self::Balance, tip: Self::Balance, paid: Self::LiquidityInfo ) -> Result<(<<T as Config>::Fungibles as Inspect<<T as Config>::AccountId>>::Balance, <<T as Config>::Fungibles as Inspect<<T as Config>::AccountId>>::Balance), TransactionValidityError>

Hand the fee and the tip over to the [HandleCredit] 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.

Returns the fee and tip in the asset used for payment as (fee, tip).

type Balance = <<T as Config>::OnChargeTransaction as OnChargeTransaction<T>>::Balance

The underlying integer type in which fees are calculated.

type AssetId = <<T as Config>::Fungibles as Inspect<<T as Config>::AccountId>>::AssetId

The type used to identify the assets used for transaction payment.

type LiquidityInfo = Imbalance<<<T as Config>::Fungibles as Inspect<<T as Config>::AccountId>>::AssetId, <<T as Config>::Fungibles as Inspect<<T as Config>::AccountId>>::Balance, <<T as Config>::Fungibles as Balanced<<T as Config>::AccountId>>::OnDropCredit, <<T as Config>::Fungibles as Balanced<<T as Config>::AccountId>>::OnDropDebt>

The type used to store the intermediate values between pre- and post-dispatch.
