Struct Run 

pub struct Run<'d> { /* private fields */ }

A workflow run, one request at a time.

Implementations

impl<'d> Run<'d>

pub fn start( description: &'d Description, options: &'d Options, ) -> Result<Self, ExecutionError>

Prepare a run: pick the workflow, order what it depends on, and stop before anything is sent.

Errors

ExecutionError::UnknownWorkflow or ExecutionError::Circular when the description does not describe a runnable order.

pub fn advance(&mut self) -> Result<Progress, ExecutionError>

Advance until something is needed from the caller.

Not called next: a run is not an iterator, because what comes out of it has to be answered with Run::supply before there is anything more to come.

Errors

Whatever stopped the run — see ExecutionError.

pub fn supply(&mut self, response: HttpResponse) -> Result<(), ExecutionError>

Hand back the response to the request Run::advance asked for.

Errors

Whatever the response made impossible — a criterion that cannot be decided, an output that names nothing, a goto with no target.
