Enum Ask 

pub enum Ask {
    Declaration(&'static FormQuestion),
    Skippable(&'static SkippableQuestion),
}

One thing income answer asks: a MANDATORY declaration (from the FORM_QUESTIONS registry — a bare Enter with nothing on file is refused, never accepted as an answer) or a SKIPPABLE prompt (from the core SKIPPABLE_QUESTIONS registry — a bare Enter leaves None, forgoing the benefit lawfully).

Variants

Declaration(&'static FormQuestion)

Skippable(&'static SkippableQuestion)

Implementations

impl Ask

pub fn declaration_id(&self) -> Option<QuestionId>

The registry QuestionId if this is a declaration — for tests that assert WHICH questions are live.

pub fn is_skippable(&self) -> bool

Whether a bare Enter with nothing on file is a legitimate outcome. True for skippables (DOBs), false for declarations — silence on a declaration is exactly what D-8 forbids.
