Struct zebra_chain::history_tree::NonEmptyHistoryTree

impl NonEmptyHistoryTree

pub fn from_cache( network: Network, size: u32, peaks: BTreeMap<u32, Entry>, current_height: Height ) -> Result<Self, HistoryTreeError>

Recreate a HistoryTree from previously saved data.

The parameters must come from the values of NonEmptyHistoryTree::size, NonEmptyHistoryTree::peaks and NonEmptyHistoryTree::current_height of a HistoryTree.

pub fn from_block( network: Network, block: Arc<Block>, sapling_root: &Root, orchard_root: &Root ) -> Result<Self, HistoryTreeError>

Create a new history tree with a single block.

sapling_root is the root of the Sapling note commitment tree of the block. orchard_root is the root of the Orchard note commitment tree of the block; (ignored for pre-Orchard blocks).

pub fn push( &mut self, block: Arc<Block>, sapling_root: &Root, orchard_root: &Root ) -> Result<(), HistoryTreeError>

Add block data to the tree.

sapling_root is the root of the Sapling note commitment tree of the block. orchard_root is the root of the Orchard note commitment tree of the block; (ignored for pre-Orchard blocks).

§Panics

If the block height is not one more than the previously pushed block.
