pub struct SqliteStore { /* private fields */ }
Expand description

SQLite-backed Store implementation.

Current table definitions are the result of applying every migration under migrations/ in order.

Implementations§

Source§

impl SqliteStore

Source

pub fn get_foreign_account_code( conn: &mut Connection, account_ids: Vec<AccountId>, ) -> Result<BTreeMap<AccountId, AccountCode>, StoreError>

Source

pub fn get_account_vault( conn: &Connection, account_id: AccountId, ) -> Result<AssetVault, StoreError>

Retrieves the full asset vault for a specific account.

Source

pub fn get_account_storage( conn: &Connection, account_id: AccountId, filter: &AccountStorageFilter, ) -> Result<AccountStorage, StoreError>

Retrieves the full storage for a specific account.

Source

pub fn upsert_foreign_account_code( conn: &mut Connection, account_id: AccountId, code: &AccountCode, ) -> Result<(), StoreError>

Source

pub fn prune_account_history( conn: &mut Connection, account_id: AccountId, up_to_nonce: Felt, ) -> Result<usize, StoreError>

Prunes historical account states for a single account up to the given nonce.

Deletes all historical entries with replaced_at_nonce <= up_to_nonce (see DESIGN.md for why this threshold is safe), then removes any account code that was only referenced by the deleted headers.

Source§

impl SqliteStore

Source

pub fn prune_irrelevant_blocks( conn: &mut Connection, blocks_to_untrack: &[BlockNumber], node_indices_to_remove: &[InOrderIndex], ) -> Result<(), StoreError>

Prunes irrelevant block data from the store.

This performs three operations in a single transaction:

  1. Deletes MMR authentication nodes at the given node_indices.
  2. Sets has_client_notes = false for blocks_to_untrack.
  3. Deletes block headers with has_client_notes = false that are not the genesis or sync-height block.
Source§

impl SqliteStore

Source

pub fn get_transactions( conn: &mut Connection, filter: &TransactionFilter, ) -> Result<Vec<TransactionRecord>, StoreError>

Retrieves tracked transactions, filtered by TransactionFilter.

Source

pub fn apply_transaction( conn: &mut Connection, tx_update: &TransactionStoreUpdate, ) -> Result<(), StoreError>

Inserts a transaction and updates the current state based on the tx_result changes.

SQL writes and forest mutations go through the same rusqlite transaction, so they commit or roll back atomically.

Source

pub fn apply_transaction_batch( conn: &mut Connection, tx_updates: &[TransactionStoreUpdate], ) -> Result<(), StoreError>

Applies a batch of TransactionStoreUpdates atomically. Either every update in the slice is persisted or none are. Executes in order inside a single rusqlite::Transaction.

Source§

impl SqliteStore

Source

pub async fn new(database_filepath: PathBuf) -> Result<Self, StoreError>

Returns a new instance of Store instantiated with the specified configuration options.

Source

pub fn database_filepath(&self) -> &Path

Returns the path of the database file backing this store.
