Trait ExecutableQuery 

pub trait ExecutableQuery<Q>: WorkflowImplementation
where
    Q: QueryDefinition,
{
    // Required method
    fn handle(
        &self,
        ctx: &WorkflowContextView,
        input: <Q as QueryDefinition>::Input,
    ) -> Result<<Q as QueryDefinition>::Output, Box<dyn Error + Sync + Send>>;

    // Provided method
    fn dispatch(
        &self,
        ctx: &WorkflowContextView,
        input: Box<dyn Any>,
        converter: &PayloadConverter,
    ) -> Result<Payload, WorkflowError> { ... }
}

Trait for executing query handlers on a workflow.

Required Methods

fn handle( &self, ctx: &WorkflowContextView, input: <Q as QueryDefinition>::Input, ) -> Result<<Q as QueryDefinition>::Output, Box<dyn Error + Sync + Send>>

Handle a query with the given input and return the result.

Provided Methods

fn dispatch( &self, ctx: &WorkflowContextView, input: Box<dyn Any>, converter: &PayloadConverter, ) -> Result<Payload, WorkflowError>

Dispatch the query with an already decoded input.

Dyn Compatibility

This trait is not dyn compatible.

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