}

A transaction over a dynamic table.

Dropping one does not abort it: neither transport can abort reliably from Drop, and a silent best-effort attempt would be a lie. An unfinished transaction expires on the server after its timeout.

Required Methods

fn id(&self) -> String

The transaction id, as the cluster shows it.

fn lookup_rows( &self, path: &str, keys: &[Row], options: &LookupOptions, ) -> Result<Vec<MaybeRow>>

Looks rows up as of this transaction.

fn select_rows(&self, query: &str, options: &SelectOptions) -> Result<Vec<Row>>

Runs a query as of this transaction.

fn insert_rows(&self, path: &str, rows: &[Row]) -> Result<()>

Writes rows in this transaction.

fn delete_rows(&self, path: &str, keys: &[Row]) -> Result<()>

Deletes rows by key in this transaction.

fn ping(&self) -> Result<()>

Tells the server the transaction is still wanted.

fn commit(self: Box<Self>) -> Result<()>

Commits. Takes the transaction by box because it consumes it.

fn abort(self: Box<Self>) -> Result<()>

Aborts.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
