Enum Answer 

pub enum Answer {
    String(String),
    Int(i128),
}

Represents an Advent of Code integer or string puzzle answer. Answers may or may not be valid solutions.

use advent_of_code_data::Answer;

let string_answer = Answer::String("hello world".to_string());
let int_answer = Answer::Int(42);

Automatic Conversions

Answer implements From for common string and integer types:

• String, &str->Answer::String`
• Numeric types (i8, i16, i32, i64, isize, usize, etc) -> Answer::Int

use advent_of_code_data::Answer;

let string_answer: Answer = "hello world".into();
assert_eq!(string_answer, Answer::String("hello world".to_string()));

let int_answer: Answer = 42.into();
assert_eq!(int_answer, Answer::Int(42));

FromStr (string parsing)

Answer supports string parsing for both integer and string values.

use advent_of_code_data::Answer;

let answer: Answer = "testing 123".parse::<Answer>().unwrap();
assert_eq!(answer, Answer::String("testing 123".to_string()));

let answer: Answer = "-5713".parse::<Answer>().unwrap();
assert_eq!(answer, Answer::Int(-5713));

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl PartialEq for Answer

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