Attribute Macro workflow_methods 

#[workflow_methods]

Defines workflow methods for a workflow struct. Using this macro requires that you also depend on the temporalio_sdk crate.

This macro processes an impl block and generates:

• Marker structs for each workflow method
• Trait implementations for workflow definition and execution
• Registration code for workers

Macro Attributes

• factory_only - When set, the workflow must be registered using register_workflow_with_factory and does not need to implement Default or define an #[init] method. Ex: #[workflow_methods(factory_only)]

Method Attributes

• #[init] - Optional initialization method. Signature: fn new(input: T, ctx: &WorkflowContext) -> Self
• #[run] - Required main workflow function. Signature: async fn run(&mut self, ctx: &mut WorkflowContext) -> WorkflowResult<T>
• #[signal] - Signal handler. Sync: fn signal(&mut self, ctx: &mut SyncWorkflowContext, input: T). Async: async fn signal(ctx: &mut WorkflowContext, input: T)
• #[query] - Query handler. Signature: fn query(&self, ctx: &WorkflowContextView, input: T) -> R (must NOT be async)
• #[update] - Update handler. Sync: fn update(&mut self, ctx: &mut SyncWorkflowContext, input: T) -> R. Async: async fn update(ctx: &mut WorkflowContext, input: T) -> R

For a usage example, see the temporalio_sdk crate’s documentation.
