Struct pallet_xcm_bridge_hub::BridgeId

pub struct BridgeId(/* private fields */);

Bridge identifier - used only for communicating with sibling/parent chains in the same consensus.

For example, SendXcm implementations (which use the latest XCM) can use it to identify a bridge and the corresponding LaneId that is used for over-consensus communication between bridge hubs.

This identifier is constructed from the latest XCM, so it is expected to ensure migration to the latest XCM version. This could change the BridgeId, but it will not affect the LaneId. In other words, LaneId will never change, while BridgeId could change with (every) XCM upgrade.

Implementations

impl BridgeId

pub fn new( universal_source: &Junctions, universal_destination: &Junctions, ) -> BridgeId

Create bridge identifier from two universal locations.

Note: The BridgeId is constructed from latest XCM, so if stored, you need to ensure compatibility with newer XCM versions.

Trait Implementations

Convert self to a slice and append it to the destination.

fn encode(&self) -> Vec<u8>

Convert self to an owned vector.

fn using_encoded<__CodecOutputReturn, __CodecUsingEncodedCallback>( &self, f: __CodecUsingEncodedCallback, ) -> __CodecOutputReturn
