Struct Roman 

pub struct Roman { /* private fields */ }

The main struct for romantic.

Implementations

impl Roman

pub fn new(character_set: &[char]) -> Self

Creates a new Roman using the characters in character_set.

The order of the character_set determines their magnitude, for example using the default numeral system:

Index	Magnitude	Character
0	1	‘I’
1	5	‘V’
2	10	‘X’
3	50	‘L’
4	100	‘C’
5	500	‘D’
6	1000	‘M’
…	…	…

Example

use romantic::Roman;

let roman = Roman::default();
assert_eq!(roman.to_string(9).unwrap(), "IX");
assert_eq!(roman.from_str::<i32>("IX").unwrap(), 9);

let custom = Roman::new(&['A', 'B', 'C']);
assert_eq!(custom.to_string(9).unwrap(), "AC");
assert_eq!(custom.from_str::<i32>("AC").unwrap(), 9);

pub fn from_str<T: PrimInt>(&self, input: &str) -> Result<T, ConversionError>

Converts a str to a generic integer num::PrimInt.

Example

use romantic::Roman;

let roman = Roman::default();
assert_eq!(roman.from_str::<i32>("IX").unwrap(), 9);

let custom = Roman::new(&['A', 'B', 'C']);
assert_eq!(custom.from_str::<i32>("AC").unwrap(), 9);

pub fn to_string<T: PrimInt + ToString>( &self, number: T, ) -> Result<String, ConversionError>

Converts a generic integer num::PrimInt to a String.

Example

use romantic::Roman;

let roman = Roman::default();
assert_eq!(roman.to_string(9).unwrap(), "IX");

let custom = Roman::new(&['A', 'B', 'C']);
assert_eq!(custom.to_string(9).unwrap(), "AC");
