Struct ScannedBundles

Source 
pub struct ScannedBundles<NoteCommitment, NF> { /* private fields */ }
Expand description

The protocol-specific note commitment and nullifier data extracted from the per-transaction shielded bundles in CompactBlock, used by the wallet for note commitment tree maintenance and spend detection.

Implementations§

Source§

impl<NoteCommitment, NF> ScannedBundles<NoteCommitment, NF>

Source

pub fn final_tree_size(&self) -> u32

Returns the size of the note commitment tree as of the end of the scanned block.

Source

pub fn nullifier_map(&self) -> &[(TxId, u16, Vec<NF>)]

Returns the vector of nullifiers for each transaction in the block.

The returned tuple is keyed by both transaction ID and the index of the transaction within the block, so that either the txid or the combination of the block hash available from ScannedBlock::block_hash and returned transaction index may be used to uniquely identify the transaction, depending upon the needs of the caller.

Source

pub fn commitments(&self) -> &[(NoteCommitment, Retention<BlockHeight>)]

Returns the ordered list of note commitments to be added to the note commitment tree.
