}

Trait for executing asynchronous update handlers on a workflow.

Required Methods

fn handle( ctx: WorkflowContext<Self>, input: U::Input, ) -> LocalBoxFuture<'static, Result<U::Output, Box<dyn Error + Send + Sync>>>

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

Provided Methods

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

Validate an update before it is applied.

fn dispatch( ctx: WorkflowContext<Self>, input: Box<dyn Any>, converter: &PayloadConverter, ) -> LocalBoxFuture<'static, 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".
