Struct cumulus_pallet_parachain_system::consensus_hook::ExpectParentIncluded

source · 
pub struct ExpectParentIncluded;
Expand description

A special consensus hook for handling the migration to asynchronous backing gracefully, even if collators haven’t been updated to provide the last included parent in the state proof yet.

This behaves as though the parent is included, even if the relay chain state proof doesn’t contain the included para head. If the para head is present in the state proof, this does ensure the parent is included.
