Struct rug::rational::ValidRational

pub struct ValidRational<'a> { /* fields omitted */ }

A validated string that can always be converted to a Rational.

See the Rational::valid_str_radix method.

Examples

use rug::Rational;
use rug::rational::ValidRational;
// This string is correct in radix 10, it cannot fail.
let s = "123/456";
let valid: ValidRational = match Rational::valid_str_radix(s, 10) {
    Ok(valid) => valid,
    Err(_) => unreachable!(),
};
let r = Rational::from(valid);
assert_eq!(r, (123, 456));
