Struct pallet_asset_conversion_tx_payment::ChargeAssetTxPayment

pub struct ChargeAssetTxPayment<T: Config> { /* private fields */ }

Require payment for transaction inclusion and optionally include a tip to gain additional priority in the queue. Allows paying via both Currency as well as fungibles::Balanced.

Wraps the transaction logic in [pallet_transaction_payment] and extends it with assets. An asset ID of None falls back to the underlying transaction payment logic via the native currency.
