Trait for executing synchronous update handlers on a workflow.

Required Methods

fn handle( &mut self, ctx: &mut SyncWorkflowContext<Self>, input: <U as UpdateDefinition>::Input, ) -> Result<<U as UpdateDefinition>::Output, Box<dyn Error + Sync + Send>>

Handle an update with the given input and return the result.

Provided Methods

fn validate( &self, _ctx: &WorkflowContextView, _input: &<U as UpdateDefinition>::Input, ) -> Result<(), Box<dyn Error + Sync + Send>>

Validate an update before it is applied.

fn dispatch( ctx: WorkflowContext<Self>, input: Box<dyn Any>, converter: &PayloadConverter, ) -> Pin<Box<dyn Future<Output = Result<Payload, WorkflowError>>>>

Dispatch the update with an already decoded input.

fn dispatch_validate( &self, ctx: &WorkflowContextView, input: Box<dyn Any>, ) -> Result<(), WorkflowError>

Dispatch validation with an already decoded input.

Dyn Compatibility

This trait is not dyn compatible.

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