Struct NoteStore 

pub struct NoteStore { /* private fields */ }

Stores discovered notes indexed by siloed nullifier (unique key).

Phase 2 enhanced version with:

• Scope-based access control
• Nullification with block number tracking
• Status filtering (Active/Nullified/Both)
• Rollback support for chain reorgs
• Batch note addition

Implementations

impl NoteStore

pub fn new(kv: Arc<dyn KvStore>) -> NoteStore

pub async fn add_notes( &self, notes: &[StoredNote], scope: &AztecAddress, ) -> Result<(), Error>

Add multiple notes at once.

pub async fn add_note(&self, note: &StoredNote) -> Result<(), Error>

Add a single discovered note (backward compatible).

pub async fn get_notes( &self, filter: &NoteFilter, ) -> Result<Vec<StoredNote>, Error>

Get notes matching a filter.

pub async fn get_notes_by_slot( &self, contract: &AztecAddress, storage_slot: &Fr, ) -> Result<Vec<StoredNote>, Error>

Get notes for a contract and storage slot (backward compatible).

pub async fn apply_nullifiers( &self, nullifiers: &[(Fr, u64)], ) -> Result<(), Error>

Apply nullifiers: mark notes as nullified with block number tracking.

pub async fn nullify_note( &self, contract: &AztecAddress, storage_slot: &Fr, note_hash: &Fr, ) -> Result<(), Error>

Mark a note as nullified (backward compatible).

pub async fn rollback( &self, block_number: u64, _synced_block_number: u64, ) -> Result<(), Error>

Rollback: undo nullifications and delete notes after a given block.

pub async fn has_note( &self, contract: &AztecAddress, note_hash: &Fr, ) -> Result<bool, Error>

Check if a note hash exists in the store (active only).
