Enum ActionResult 

pub enum ActionResult {
    StartWith(Box<dyn Value>),
    Finished(StateData),
    CannotFulfill,
}

The result of Action::start()

Variants

StartWith(Box<dyn Value>)

The action requires the caller to fulfill the Step’s outputs. The value’s meaning is Action dependent. When the caller obtains the output data (i.e. with a form), it can then advance the Session.

if let ActionResult::StartWith(uri) = action_result {
  respond_with_redirect(uri.downcast::<StringValue>().unwrap())
}

Finished(StateData)

The action fulfilled the ouputs with the results in the StateData.

CannotFulfill

The action was not able to fulfill the ouputs as a result of a normal condition such as a minimum time duration. This should not be used for error situations.

Trait Implementations

impl Clone for ActionResult

fn clone(&self) -> ActionResult

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ActionResult

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for ActionResult

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
