Trait golem_rust::Operation

pub trait Operation: Clone {
    type In: Clone;
    type Out: Clone;
    type Err: Clone;

    // Required methods
    fn execute(&self, input: Self::In) -> Result<Self::Out, Self::Err>;
    fn compensate(
        &self,
        input: Self::In,
        result: Self::Out,
    ) -> Result<(), Self::Err>;
}

Represents an atomic operation of the transaction which has a rollback action.

Implement this trait and use it within a transaction block. Operations can also be constructed from closures using operation.
