pub struct BlockNoteTree(/* private fields */);Expand description
Wrapper over SimpleSmt<BLOCK_NOTE_TREE_DEPTH> for notes tree.
Each note is stored as two adjacent leaves: odd leaf for id, even leaf for metadata hash. ID’s leaf index is calculated as [(batch_idx * MAX_NOTES_PER_BATCH + note_idx_in_batch) * 2]. Metadata hash leaf is stored the next after id leaf: [id_index + 1].
Implementations§
Source§impl BlockNoteTree
impl BlockNoteTree
Sourcepub fn with_entries(
entries: impl IntoIterator<Item = (BlockNoteIndex, NoteId, NoteMetadata)>,
) -> Result<Self, MerkleError>
pub fn with_entries( entries: impl IntoIterator<Item = (BlockNoteIndex, NoteId, NoteMetadata)>, ) -> Result<Self, MerkleError>
Returns a new BlockNoteTree instantiated with entries set as specified by the provided entries.
Entry format: (note_index, note_id, note_metadata).
Value of each leaf is computed as: hash(note_id || note_metadata).
All leaves omitted from the entries list are set to crate::EMPTY_WORD.
§Errors
Returns an error if:
- The number of entries exceeds the maximum notes tree capacity, that is 2^16.
- The provided entries contain multiple values for the same key.
Sourcepub fn get_note_path(&self, index: BlockNoteIndex) -> MerklePath
pub fn get_note_path(&self, index: BlockNoteIndex) -> MerklePath
Returns merkle path for the note with specified batch/note indexes.
