Struct pallet_asset_conversion_tx_payment::AssetConversionAdapter

pub struct AssetConversionAdapter<C, CON>(_);

Implements the asset transaction for a balance to asset converter (implementing [Swap]).

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

Trait Implementations

impl<T, C, CON> OnChargeAssetTransaction<T> for AssetConversionAdapter<C, CON>where T: Config, C: Inspect<<T as Config>::AccountId>, CON: Swap<T::AccountId, T::HigherPrecisionBalance, T::MultiAssetId>, T::HigherPrecisionBalance: From<<<T as Config>::OnChargeTransaction as OnChargeTransaction<T>>::Balance> + TryInto<<<T as Config>::Fungibles as Inspect<<T as Config>::AccountId>>::Balance>, T::MultiAssetId: From<<<T as Config>::Fungibles as Inspect<<T as Config>::AccountId>>::AssetId>, <<T as Config>::OnChargeTransaction as OnChargeTransaction<T>>::Balance: IsType<<C as Inspect<<T as Config>::AccountId>>::Balance>,

Default implementation for a runtime instantiating this pallet, an asset to native swapper.

fn withdraw_fee( who: &T::AccountId, call: &T::RuntimeCall, info: &DispatchInfoOf<T::RuntimeCall>, asset_id: Self::AssetId, fee: <<T as Config>::OnChargeTransaction as OnChargeTransaction<T>>::Balance, tip: <<T as Config>::OnChargeTransaction as OnChargeTransaction<T>>::Balance ) -> Result<(<<T as Config>::OnChargeTransaction as OnChargeTransaction<T>>::LiquidityInfo, Self::LiquidityInfo, <<T as Config>::Fungibles as Inspect<<T as Config>::AccountId>>::Balance), TransactionValidityError>

Swap & withdraw the predicted fee from the transaction origin.

Note: The fee already includes the tip.

Returns the total amount in native currency received by exchanging the asset_id and the amount in native currency used to pay the fee.

fn correct_and_deposit_fee( who: &T::AccountId, dispatch_info: &DispatchInfoOf<T::RuntimeCall>, post_info: &PostDispatchInfoOf<T::RuntimeCall>, corrected_fee: <<T as Config>::OnChargeTransaction as OnChargeTransaction<T>>::Balance, tip: <<T as Config>::OnChargeTransaction as OnChargeTransaction<T>>::Balance, fee_paid: <<T as Config>::OnChargeTransaction as OnChargeTransaction<T>>::LiquidityInfo, received_exchanged: Self::LiquidityInfo, asset_id: Self::AssetId, initial_asset_consumed: <<T as Config>::Fungibles as Inspect<<T as Config>::AccountId>>::Balance ) -> Result<<<T as Config>::Fungibles as Inspect<<T as Config>::AccountId>>::Balance, TransactionValidityError>

Correct the fee and swap the refund back to asset.

Note: The corrected_fee already includes the tip. Note: Is the ED wasn’t needed, the received_exchanged will be equal to fee_paid, or fee_paid + ed otherwise.

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

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