Struct rug::rational::ParseRationalError

pub struct ParseRationalError { /* fields omitted */ }

An error which can be returned when parsing a Rational number.

Examples

use rug::Rational;
use rug::rational::ParseRationalError;
// This string is not a rational number.
let s = "something completely different (_!_!_)";
let error: ParseRationalError = match Rational::valid_str_radix(s, 4) {
    Ok(_) => unreachable!(),
    Err(error) => error,
};
println!("Parse error: {:?}", error);
