pub struct PartialNullifierTree(/* private fields */);Expand description
The partial sparse merkle tree containing the nullifiers of consumed notes.
Implementations§
Source§impl PartialNullifierTree
impl PartialNullifierTree
Sourcepub const UNSPENT_NULLIFIER: Word = EMPTY_WORD
pub const UNSPENT_NULLIFIER: Word = EMPTY_WORD
The leaf value of an unspent nullifier.
Sourcepub fn add_nullifier_witness(
&mut self,
witness: NullifierWitness,
) -> Result<(), NullifierTreeError>
pub fn add_nullifier_witness( &mut self, witness: NullifierWitness, ) -> Result<(), NullifierTreeError>
Adds the given nullifier witness to the partial tree and tracks it. Once a nullifier has
been added to the tree, it can be marked as spent using Self::mark_spent.
§Errors
Returns an error if:
- after the witness’ merkle path was added the partial nullifier tree has a different root than before it was added.
Sourcepub fn mark_spent(
&mut self,
nullifiers: impl Iterator<Item = Nullifier>,
block_num: BlockNumber,
) -> Result<(), NullifierTreeError>
pub fn mark_spent( &mut self, nullifiers: impl Iterator<Item = Nullifier>, block_num: BlockNumber, ) -> Result<(), NullifierTreeError>
Marks the given nullifiers as spent at the given block number.
§Errors
Returns an error if:
- a nullifier was already spent.
- a nullifier is not tracked by this partial nullifier tree, that is, its
NullifierWitnesswas not added to the tree previously.
