Struct Questions 

pub struct Questions<'a> { /* private fields */ }

The questions of one call, keyed by the names their answers come back under.

The order questions are added in is the order they are sent in. Adding a name that is already there replaces that question and keeps its position, as the upstream SDK’s dictionary does.

Nothing is checked until prepare, which validates and serializes the whole set once.

Implementations

impl<'a> Questions<'a>

pub fn new() -> Self

An empty question set.

pub fn question( self, name: impl Into<Cow<'a, str>>, question: impl Into<Question<'a>>, ) -> Self

Adds a question of any kind under name.

pub fn noul(self, name: impl Into<Cow<'a, str>>, question: Noul<'a>) -> Self

Adds a yes/no question under name.

pub fn choice(self, name: impl Into<Cow<'a, str>>, question: Choice<'a>) -> Self

Adds a choice question under name.

pub fn score(self, name: impl Into<Cow<'a, str>>, question: Score<'a>) -> Self

Adds a score question under name.

pub fn raw( self, name: impl Into<Cow<'a, str>>, question: RawQuestion<'a>, ) -> Self

Adds a raw question under name.

pub fn prepare(self) -> Result<PreparedQuestions, Error>

Validates the set and serializes it into the bytes every call will send.

Errors

Returns an ErrorKind::InvalidRequest error, with the upstream SDK’s message, when the set is empty, when a score has no levels, when a raw question’s type is not a nonempty string, when a raw choice or score has no criteria, when a raw score’s criteria is empty, or when a raw question’s field could not be encoded. The first failing question, in order, is the one reported.
