Struct SovereignPaidRemoteExporter 

pub struct SovereignPaidRemoteExporter<Bridges, Router, UniversalLocation>(/* private fields */);

Implementation of SendXcm which wraps the message inside an ExportMessage instruction and sends it to a destination known to be able to handle it.

The ExportMessage instruction on the bridge is paid for from the local chain’s sovereign account on the bridge. The amount paid is determined through the ExporterFor trait.

The XcmHash value returned by deliver will always be the same as that returned by the message exporter (Bridges). Generally this should take notice of the message should it end with the SetTopic instruction.

In the case that the message ends with a SetTopic(T) (as should be the case if the top-level router is WithUniqueTopic), then the forwarding message (i.e. the one carrying the export instruction to the bridge in local consensus) will also end with the same SetTopic(T). If this is not the case, then the onward message will not be given the SetTopic afterward.

Trait Implementations

impl<Bridges, Router, UniversalLocation> InspectMessageQueues for SovereignPaidRemoteExporter<Bridges, Router, UniversalLocation>

fn get_messages() -> Vec<(VersionedLocation, Vec<VersionedXcm<()>>)>

This router needs to implement InspectMessageQueues but doesn’t have to return any messages, since it just reuses the XcmpQueue router.

fn clear_messages()

Clear the queues at the beginning of Runtime API call, so that subsequent Self::get_messages() will return only messages generated by said Runtime API.

impl<Bridges: ExporterFor, Router: SendXcm, UniversalLocation: Get<InteriorLocation>> SendXcm for SovereignPaidRemoteExporter<Bridges, Router, UniversalLocation>

type Ticket = <Router as SendXcm>::Ticket

Intermediate value which connects the two phases of the send operation.

fn validate( dest: &mut Option<Location>, msg: &mut Option<Xcm<()>>, ) -> SendResult<Router::Ticket>

Check whether the given _message is deliverable to the given _destination and if so determine the cost which will be paid by this chain to do so, returning a Validated token which can be used to enact delivery.

fn deliver(ticket: Router::Ticket) -> Result<XcmHash, SendError>

Actually carry out the delivery operation for a previously validated message sending.
