Description

SQLite3 backend for Selda.

Synopsis

Documentation

withSQLite :: (MonadIO m, MonadMask m) => FilePath -> SeldaT SQLite m a -> m a Source #

Perform the given computation over an SQLite database. The database is guaranteed to be closed when the computation terminates.

sqliteOpen :: (MonadIO m, MonadMask m) => FilePath -> m (SeldaConnection SQLite) Source #

Open a new connection to an SQLite database. The connection is reusable across calls to runSeldaT, and must be explicitly closed using seldaClose when no longer needed.

seldaClose :: MonadIO m => SeldaConnection b -> m () #

Close a reusable Selda connection. Closing a connection while in use is undefined. Passing a closed connection to runSeldaT results in a SeldaError being thrown. Closing a connection more than once is a no-op.

sqliteBackend :: Database -> SeldaBackend SQLite Source #

Create a Selda backend using an already open database handle. This is useful for situations where you want to use some SQLite-specific functionality alongside Selda.

Note that manipulating the underlying database handle directly voids any and all safety guarantees made by the Selda API. Caching functionality in particular WILL break. Proceed with extreme caution.
