Expand description

Key changes read proof.

Fields

max_block: <Header as Header>::Number

Max block that has been used in changes query.

proof: Vec<Vec<u8, Global>, Global>

All touched nodes of all changes tries.

roots: BTreeMap<<Header as Header>::Number, <Header as Header>::Hash>

All changes tries roots that have been touched AND are missing from the requester’ node. It is a map of block number => changes trie root.

roots_proof: StorageProof

The proofs for all changes tries roots that have been touched AND are missing from the requester’ node. It is a map of CHT number => proof.
