Struct NullMessageRouter

pub struct NullMessageRouter {}

A special MessageRouter that performs no routing and does not create blinded paths. Its purpose is to enable the creation of Offers and Refunds without blinded paths, where the user’s node_id is used directly as the Destination.

Note

NullMessageRouter must not be used as the type parameter for ChannelManager, since ChannelManager requires a functioning MessageRouter to create blinded paths, which are necessary for constructing reply paths in onion message communication. However, NullMessageRouter can still be passed as an argument to ChannelManager methods that accepts a MessageRouter, such as ChannelManager::create_offer_builder_using_router, when blinded paths are not needed.
