Trait golem_rust::Transaction

pub trait Transaction<Err> {
    // Required methods
    fn execute<OpIn: Clone + 'static, OpOut: Clone + 'static>(
        &mut self,
        operation: impl Operation<In = OpIn, Out = OpOut, Err = Err> + 'static,
        input: OpIn,
    ) -> Result<OpOut, Err>;
    fn fail(&mut self, error: Err) -> Result<(), Err>;
    fn run<Out>(
        f: impl FnOnce(&mut Self) -> Result<Out, Err>,
    ) -> TransactionResult<Out, Err>;
}

A unified interface for the different types of transactions. Using it can make the code easier to switch between different transactional guarantees but is more constrained in terms of error types.

Required Methods

fn execute<OpIn: Clone + 'static, OpOut: Clone + 'static>( &mut self, operation: impl Operation<In = OpIn, Out = OpOut, Err = Err> + 'static, input: OpIn, ) -> Result<OpOut, Err>

fn fail(&mut self, error: Err) -> Result<(), Err>

fn run<Out>( f: impl FnOnce(&mut Self) -> Result<Out, Err>, ) -> TransactionResult<Out, Err>

Object Safety

This trait is not object safe.
