Remote key changes read request.

Fields

changes_trie_configs: Vec<ChangesTrieConfigurationRange<<Header as Header>::Number, <Header as Header>::Hash>, Global>

All changes trie configurations that are valid within [first_block; last_block].

first_block: (<Header as Header>::Number, <Header as Header>::Hash)

Query changes from range of blocks, starting (and including) with this hash…

last_block: (<Header as Header>::Number, <Header as Header>::Hash)

…ending (and including) with this hash. Should come after first_block and be the part of the same fork.

max_block: (<Header as Header>::Number, <Header as Header>::Hash)

Only use digests from blocks up to this hash. Should be last_block OR come after this block and be the part of the same fork.

tries_roots: (<Header as Header>::Number, <Header as Header>::Hash, Vec<<Header as Header>::Hash, Global>)

Known changes trie roots for the range of blocks [tries_roots.0..max_block]. Proofs for roots of ascendants of tries_roots.0 are provided by the remote node.

storage_key: Option<PrefixedStorageKey>

Optional Child Storage key to read.

key: Vec<u8, Global>

Storage key to read.

retry_count: Option<usize>

Number of times to retry request. None means that default RETRY_COUNT is used.
