Crate num_rational_parse 

Flexible string parsing for num_rational.

This crate provides flexible string parsing for rational numbers, inspired by Python’s fractions module, allowing num_rational::Ratio to be parsed from strings with flexible formatting.

Examples

use num_rational::Ratio;
use num_rational_parse::RationalParse;

let r = Ratio::<i32>::from_str_flex("3.14").unwrap();
assert_eq!(r, Ratio::new(157, 50));

let r2 = Ratio::<i32>::from_str_flex("1.2e-2").unwrap();
assert_eq!(r2, Ratio::new(3, 250));

let r3 = Ratio::<i32>::from_str_flex("-1_000/2_000").unwrap();
assert_eq!(r3, Ratio::new(-1, 2));
