Struct SingleAssetExchangeAdapter

Source 
pub struct SingleAssetExchangeAdapter<AssetConversion, Fungibles, Matcher, AccountId>(/* private fields */);
Expand description

An adapter from [pallet_asset_conversion::SwapCredit] and [pallet_asset_conversion::QuotePrice] to xcm_executor::traits::AssetExchange.

This adapter takes just one fungible asset in give and allows only one fungible asset in want. If you need to handle more assets in either give or want, then you should use another type that implements xcm_executor::traits::AssetExchange or build your own.

This adapter also only works for fungible assets.

exchange_asset and quote_exchange_price will both return an error if there’s more than one asset in give or want.
