Struct SqliteBackend 

pub struct SqliteBackend { /* private fields */ }

A SQLite-backed Backend using bundled rusqlite (no system libsqlite3).

Implementations

impl SqliteBackend

pub fn open(path: &Path) -> Result<Self>

Open (or create) a SQLite database at path, in WAL mode with a busy timeout so co-located processes serialize cleanly rather than erroring.

pub fn in_memory() -> Result<Self>

Open an in-memory database (tests, ephemeral use).

pub fn from_connection(conn: Connection) -> Self

Wrap a connection a consumer already owns — the incremental-adoption seam. A consumer (newt’s ConversationStore, modulex’s Store) that already holds a rusqlite::Connection hands it over, keeps running its own domain SQL through SqliteBackend::connection, and gets the agent-store primitives on the same database: no second connection, no big-bang rewrite. Pragmas are the caller’s responsibility here (the connection is assumed already configured).

pub fn connection(&self) -> &Connection

Borrow the underlying SQLite connection for backend-specific (domain-table) SQL. SQLite-only by nature — the Backend trait stays the portable, backend-agnostic surface; this escape hatch is how a consumer keeps its existing rusqlite code while adopting the substrate.

Trait Implementations

impl Backend for SqliteBackend

fn dialect(&self) -> Dialect

The dialect this backend speaks.

fn exec(&self, sql: &str, params: &[Value]) -> Result<u64>

Run a statement, returning the number of rows affected.

fn query(&self, sql: &str, params: &[Value]) -> Result<Vec<Row>>

Run a query, returning all rows. Also used for RETURNING statements.
