}

Provide CHT roots. These are stored on a light client and generated dynamically on a full client.

Required methods

fn header_cht_root(
    &self,
    cht_size: NumberFor<Block>,
    block: NumberFor<Block>
) -> Result<Option<Block::Hash>>[src]

Get headers CHT root for given block. Returns None if the block is not a part of any CHT.

fn changes_trie_cht_root(
    &self,
    cht_size: NumberFor<Block>,
    block: NumberFor<Block>
) -> Result<Option<Block::Hash>>[src]

Get changes trie CHT root for given block. Returns None if the block is not a part of any CHT.
