Type Alias PayOverXcm 

pub type PayOverXcm<Interior, XcmConfig, Querier, Timeout, Beneficiary, AssetKind, AssetKindToLocatableAsset, BeneficiaryRefToLocation> = PayOverXcmWithHelper<Interior, TransferOverXcmHelper<XcmConfig, Querier, Timeout, Beneficiary, AssetKind, AssetKindToLocatableAsset, BeneficiaryRefToLocation>>;

Implementation of the frame_support::traits::tokens::Pay trait, to allow for XCM-based payments of a given Balance of some asset ID existing on some chain under ownership of some Interior location of the local chain to a particular Beneficiary. The AssetKind value is not itself bounded (to avoid the issue of needing to wrap some preexisting datatype), however a converter type AssetKindToLocatableAsset must be provided in order to translate it into a LocatableAsset, which comprises both an XCM Location describing the XCM endpoint on which the asset to be paid resides and an XCM AssetId to identify the specific asset at that endpoint.

This relies on the XCM TransferAsset instruction. A trait BeneficiaryRefToLocation must be provided in order to convert the Beneficiary reference into a location usable by TransferAsset.

PayOverXcm::pay is asynchronous, and returns a QueryId which can then be used in check_payment to check the status of the XCM transaction.

See also PayAccountId32OverXcm which is similar to this except that BeneficiaryRefToLocation need not be supplied and Beneficiary must implement Into<[u8; 32]>.

The implementation of this type assumes:

• The sending account on the remote chain is fixed (derived from the Interior location), rather than being fully configurable.
• The remote chain waives the XCM execution fee (PaysRemoteFee::No).

See also super::transfer::TransferOverXcm for a more generic implementation with a flexible sender account on the remote chain, and not making the assumption that the remote XCM execution fee is waived.
