Struct mentat_ffi::Store

pub struct Store { /* fields omitted */ }

A convenience wrapper around a single SQLite connection and a Conn. This is suitable for applications that don't require complex connection management.

Methods

impl Store

pub fn open(path: &str) -> Result<Store, MentatError>

Open a store at the supplied path, ensuring that it includes the bootstrap schema.

pub fn open_empty(path: &str) -> Result<Store, MentatError>

Returns a totally blank store with no bootstrap schema. Use open instead.

pub fn transact(&mut self, transaction: &str) -> Result<TxReport, MentatError>

impl Store

pub fn sqlite_mut(&mut self) -> &mut Connection

Intended for use from tests.

impl Store

pub fn dismantle(self) -> (Connection, Conn)

pub fn conn(&self) -> &Conn

pub fn begin_read(&'m mut self) -> Result<InProgressRead<'m, 'm>, MentatError>

pub fn begin_transaction(     &'m mut self ) -> Result<InProgress<'m, 'm>, MentatError>

pub fn cache(     &mut self,     attr: &Keyword,     direction: CacheDirection ) -> Result<(), MentatError>

pub fn register_observer(&mut self, key: String, observer: Arc<TxObserver>)

pub fn unregister_observer(&mut self, key: &String)
