Struct based::Base

pub struct Base { /* fields omitted */ }

The Base of a numeral system.

Methods

impl Base

pub fn new(base: &str) -> Base

Creates a new base from the given string slice.

The value of each character is its index in the slice, e.g. the first character has value 1, the second value 2, etc.

The behavior of the function is undefined when a character is present more than once in the given string slice.

Examples

use based::Base;

let base16 = based::Base::new("0123456789abcdef");

pub fn from_str<T: AddAssign + Default + MulAssign + From<usize>>(
    &self,
    rep: &str
) -> Result<T, UnknownChar>

Given a base and a number's representation in that base, return the number.

Returns Err if it encounters a character not in the Base.

Examples

use based::Base;

let base16 = Base::new("0123456789abcdef");
let sixteen = base16.from_str::<usize>("10");
assert_eq!(sixteen.unwrap(), 16);

pub fn rep<T: Into<usize>>(&self, val: T) -> String

Given a base and a number, return the representation of the number in the base.

Examples

use based::Base;

let base16 = Base::new("0123456789abcdef");
let sixteen = base16.rep::<usize>(16);
assert_eq!(sixteen, "10");

Trait Implementations
