Trait Implementations

impl Default for Transaction

fn default() -> Self

Returns the “default value” for a type.

impl RollbackableOperation for Transaction

fn execute(&mut self) -> Result<()>

fn rollback(&mut self) -> Result<()>

Rolls back all executed operations in reverse order, then resets the counter.

Only the operations that completed successfully are rolled back.
