Struct Answers 

pub struct Answers { /* private fields */ }

The answers of a response, looked up by question name.

The answers are kept in the order the server sent them, which is the order the questions were asked in. A lookup scans them, which for the handful of questions a call carries is faster than hashing the name. Should a document name one question twice - JSON allows it, the API does not do it - both answers are kept and a lookup finds the first.

The typed accessors (nouls and friends) filter as they iterate; nothing is copied or cached.

Implementations

impl Answers

pub fn len(&self) -> usize

How many answers there are.

pub fn is_empty(&self) -> bool

Whether there are none.

pub fn get(&self, name: &str) -> Option<&Answer>

The answer to the question called name.

pub fn noul(&self, name: &str) -> Option<&NoulAnswer>

The answer to the yes/no question called name, if there is one and it is a yes/no answer.

pub fn choice(&self, name: &str) -> Option<&ChoiceAnswer>

The answer to the choice question called name, if there is one and it is a choice answer.

pub fn score(&self, name: &str) -> Option<&ScoreAnswer>

The answer to the score question called name, if there is one and it is a score answer.

pub fn iter( &self, ) -> impl ExactSizeIterator<Item = (&str, &Answer)> + DoubleEndedIterator

Every answer with its question name, in the order received.

pub fn names(&self) -> impl ExactSizeIterator<Item = &str> + DoubleEndedIterator

The question names, in the order received.

pub fn nouls(&self) -> impl DoubleEndedIterator<Item = (&str, &NoulAnswer)>

The yes/no answers, in the order received.

pub fn choices(&self) -> impl DoubleEndedIterator<Item = (&str, &ChoiceAnswer)>

The choice answers, in the order received.

pub fn scores(&self) -> impl DoubleEndedIterator<Item = (&str, &ScoreAnswer)>

The score answers, in the order received.

Trait Implementations

impl AnswerSet for Answers

fn deserialize_answers<'de, D>( deserializer: D, context: AnswerContext, ) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Reads the answers object of a response.

impl Clone for Answers

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Answers

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

Formats the value using the given formatter.

impl Default for Answers

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Answers

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Reads answers with no expectation about their number. Answers of a type this version does not model are skipped, as they are in a response.

Reloading is supported through a JSON codec (sonic-rs, serde_json); see ScoreAnswer for what a non-JSON serde format cannot read back.

impl<S> FromIterator<(S, Answer)> for Answers

where S: Into<String>,

fn from_iter<I>(iter: I) -> Self

where I: IntoIterator<Item = (S, Answer)>,

Creates a value from an iterator.

impl PartialEq for Answers

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

Equality operator ==.

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

Inequality operator !=.

impl Serialize for Answers

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
