fn execute( &mut self, sql: &str, params: &[Value], ) -> impl Future<Output = Result<u64, RelError>> + Send

As RelationalBackend::execute, inside the transaction.

Source

fn query( &mut self, sql: &str, params: &[Value], ) -> impl Future<Output = Result<Vec<Row>, RelError>> + Send

As RelationalBackend::query, inside the transaction.

Source

fn commit(self) -> impl Future<Output = Result<(), RelError>> + Send

Commit.

Source

fn rollback(self) -> impl Future<Output = Result<(), RelError>> + Send

Roll back.

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