Struct staging_xcm_builder::WithTopicSource

source · 
pub struct WithTopicSource<Inner, TopicSource>(/* private fields */);
Expand description

Wrapper router which, if the message does not already end with a SetTopic instruction, prepends one to the message filled with an ID from TopicSource. This ID is returned from a successful deliver.

This is designed to be at the top-level of any routers, since it will always mutate the passed message reference into a None. Don’t try to combine it within a tuple except as the last element.

Trait Implementations§

source§

impl<Inner: SendXcm, TopicSource: SourceTopic> SendXcm for WithTopicSource<Inner, TopicSource>

§

type Ticket = (<Inner as SendXcm>::Ticket, [u8; 32])

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

fn validate( destination: &mut Option<MultiLocation>, message: &mut Option<Xcm<()>> ) -> SendResult<Self::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 more
source§

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

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