pub struct SovereignPaidRemoteExporter<Bridges, Router, UniversalLocation>(/* private fields */);Expand description
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 a SetTopic whose
inner is forward_id_for(T). If this is not the case then the onward message will not be given
the SetTopic afterword.

impl<Bridges, Router, UniversalLocation> InspectMessageQueues for SovereignPaidRemoteExporter<Bridges, Router, UniversalLocation>
source§fn get_messages() -> Vec<(VersionedLocation, Vec<VersionedXcm<()>>)>
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.
source§fn clear_messages()
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.source§impl<Bridges: ExporterFor, Router: SendXcm, UniversalLocation: Get<InteriorLocation>> SendXcm for SovereignPaidRemoteExporter<Bridges, Router, UniversalLocation>

§type Ticket = <Router as SendXcm>::Ticket
type Ticket = <Router as SendXcm>::Ticket
Intermediate value which connects the two phases of the send operation.

dest: &mut Option<Location>,
msg: &mut Option<Xcm<()>>,
) -> SendResult<Router::Ticket>
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. Read moresource§fn deliver(ticket: Router::Ticket) -> Result<XcmHash, SendError>
fn deliver(ticket: Router::Ticket) -> Result<XcmHash, SendError>
Actually carry out the delivery operation for a previously validated message sending.
source§fn ensure_successful_delivery(location: Option<Location>)
fn ensure_successful_delivery(location: Option<Location>)
Ensure
[Self::delivery] is successful for the given location when called in benchmarks.Auto Trait Implementations§
