Struct WorkflowRegistration

Source

pub struct WorkflowRegistration {
    pub name: &'static str,
    pub resume_fn: fn(Ctx) -> Pin<Box<dyn Future<Output = Result<(), DurableError>> + Send>>,
}

Expand description

A compiled-in registration of a workflow function for automatic crash recovery.

Produced by #[durable::workflow] and collected at link time by inventory. Only workflows with a single ctx: Ctx parameter are registered.

Fields§

§name: &'static str

The workflow name — must match the name passed to Ctx::start.

§resume_fn: fn(Ctx) -> Pin<Box<dyn Future<Output = Result<(), DurableError>> + Send>>

Resumes the workflow given a Ctx. Return type is erased; during recovery we only care about driving the workflow to completion.
