pub struct UnpaidRemoteExporter<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.
No effort is made to make payment to the bridge for its services, so the bridge location must have been configured with a barrier rule allowing unpaid execution for this message coming from our origin.
This is only useful if we have special dispensation by the remote bridges to have the
ExportMessage instruction executed without payment.
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.

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(validation: Self::Ticket) -> Result<XcmHash, SendError>
fn deliver(validation: Self::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§
