Struct Answers 

pub struct Answers { /* private fields */ }

Stores correct and incorrect answers for a puzzle, along with hints such as “too large” and “too small”.

Implementations

impl Answers

pub fn new() -> Self

Initialize new Answers object.

pub fn correct_answer_ref(&self) -> &Option<Answer>

pub fn wrong_answers_ref(&self) -> &Vec<Answer>

pub fn low_bounds_ref(&self) -> &Option<i128>

pub fn high_bounds_ref(&self) -> &Option<i128>

pub fn check(&self, answer: &Answer) -> Option<CheckResult>

Checks if this answer is correct or incorrect according to the information stored in this Answers database.

None is returned when the supplied answer does not match any known incorrect values, and the database does not have a known correct value. When a None value is returned, the caller should submit the answer as a solution to the puzzle using the Advent of Code client. The caller should then update this object with the response depending on if the client say it was correct or incorrect.

pub fn add_wrong_answer(&mut self, answer: Answer)

Adds an answer to the list of known wrong answers.

pub fn set_correct_answer(&mut self, answer: Answer)

Sets this answer as the known correct answer.

pub fn set_low_bounds(&mut self, answer: Answer) -> i128

Sets a low boundary value in the cache.

If the cache has an existing low boundary then the highest value will be used as the new high boundary.

Any numeric answer passed to Answers::check will be returned as CheckResult::TooLow if it equals or is smaller than the low boundary.

pub fn set_high_bounds(&mut self, answer: Answer) -> i128

Sets a high boundary value in the cache.

If the cache has an existing high boundary then the lowest value will be used as the new high boundary.

Any numeric answer passed to Answers::check will be returned as CheckResult::TooHigh if it equals or is larger than the high boundary.

pub fn serialize_to_string(&self) -> String

pub fn serialize<W: Write>(&self, writer: &mut BufWriter<W>)

pub fn deserialize_from_str( text: &str, ) -> Result<Self, AnswerDeserializationError>

pub fn deserialize<R: Read>( reader: &mut BufReader<R>, ) -> Result<Self, AnswerDeserializationError>

Trait Implementations

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 PartialEq for Answers

fn eq(&self, other: &Answers) -> 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.
