Struct based::Base

pub struct Base { /* fields omitted */ }

Base represents a numeral system with single-character digits.

Methods

impl Base

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

Creates a new numeral system from the given string slice.

The value of each character is its index in the slice, e.g. the first character has value 0, the second value 1, etc.

The behavior of this 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");
