• QueryResponseStatus
  The possible state of an XCM query response.

Traits

• AssetExchange
  A service for exchanging assets.
• AssetLock
  Define a handler for notification of an asset being locked and for the unlock instruction.
• CallDispatcher
  Defines how a call is dispatched with given origin. Allows to customize call dispatch, such as adapting the origin based on the call or modifying the call.
• CheckSuspension
  Trait to determine whether the execution engine is suspended from executing a given XCM.
• ClaimAssets
  Define any handlers for the AssetClaim instruction.
• ConvertLocation
  Means of converting a location into an account identifier.

  A converter trait for origin types.
• DropAssets
  Define a handler for when some non-empty Assets value should be dropped.
• Enact
• ExportXcm
  Utility for delivering a message to a system under a different (non-local) consensus with a spoofed origin. This essentially defines the behaviour of the ExportMessage XCM instruction.
• FeeManager
  Handle stuff to do with taking fees in certain XCM instructions.
• FilterAssetLocationDeprecated
  Filters assets/location pairs.
• MatchesFungible
• MatchesFungibles
• MatchesNonFungible
• MatchesNonFungibles
• OnResponse
  Define what needs to be done upon receiving a query response.
• QueryHandler
  Provides methods to expect responses from XCMs and query their status.
• ShouldExecute
  Trait to determine whether the execution engine should actually execute a given XCM.
• TransactAsset
  Facility for asset transacting.
• VersionChangeNotifier
  Trait for a type which handles notifying a destination of XCM version changes.
• WeightBounds
  Determine the weight of an XCM message.
• WeightTrader
  Charge for weight in order to execute XCM.

Functions

• export_xcm
  Convenience function for using a SendXcm implementation. Just interprets the dest and wraps both in Some before passing them as as mutable references into T::send_xcm.
• validate_export
  Convenience function for using a SendXcm implementation. Just interprets the dest and wraps both in Some before passing them as as mutable references into T::send_xcm.
