Module pallet_xcm_bridge::congestion

The module contains utilities for handling congestion between the bridge hub and routers.

Structs

• BlobDispatcherWithChannelStatus
  Adapter that ties together the [DispatchBlob] trait with the DispatchChannelStatusProvider trait. The idea is that [DispatchBlob] triggers message dispatch/delivery on the receiver side, while DispatchChannelStatusProvider provides a status check to ensure the dispatch channel is active (not congested).
• CongestionLimits
  Limits for handling congestion.
• HereOrLocalConsensusXcmChannelManager
  Switches the implementation of LocalXcmChannelManager based on the local_origin.
• UpdateBridgeStatusXcmChannelManager
  Manages the local XCM channels by sending XCM messages with the update_bridge_status extrinsic to the local_origin. The XcmProvider type converts the encoded call to XCM, which is then sent by XcmSender to the local_origin. This is useful, for example, when a router with [xcm::prelude::ExportMessage] is deployed on a different chain, and we want to control congestion by sending XCMs.
