Struct cumulus_primitives_utility::ParentAsUmp

source · 
pub struct ParentAsUmp<T, W, P>(/* private fields */);
Expand description

Xcm router which recognises the Parent destination and handles it by sending the message into the given UMP UpwardMessageSender implementation. Thus this essentially adapts an UpwardMessageSender trait impl into a SendXcm trait impl.

NOTE: This is a pretty dumb “just send it” router; we will probably want to introduce queuing to UMP eventually and when we do, the pallet which implements the queuing will be responsible for the SendXcm implementation.

Trait Implementations§

source§

impl<T: UpwardMessageSender + InspectMessageQueues, W, P> InspectMessageQueues for ParentAsUmp<T, W, P>

source§

fn clear_messages()

source§

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

Get queued messages and their destinations.

source§

fn validate( dest: &mut Option<Location>, msg: &mut Option<Xcm<()>>, ) -> SendResult<Vec<u8>>
