Expand description
Implementors are able to create a new read-write DB transaction
Required Methods§
sourcefn with_commit_sync<E, R, F>(&'e mut self, f: F) -> Result<R, E>
fn with_commit_sync<E, R, F>(&'e mut self, f: F) -> Result<R, E>
Run a closure, passing in a mutable reference to a read-write transaction, and commit the transaction after the closure has run. If there is a SQLite error, recover from it and re-run the closure.
Provided Methods§
fn with_commit_test<R, F>(&'e mut self, f: F) -> Result<R, DatabaseError>where
F: 'e + FnOnce(&mut Transaction<'_>) -> R,
