Struct rug::integer::TryFromIntegerError

pub struct TryFromIntegerError { /* fields omitted */ }

An error which can be returned when a checked conversion from Integer fails.

Examples

use core::convert::TryFrom;
use rug::{integer::TryFromIntegerError, Integer};
// This is negative and cannot be converted to u32.
let i = Integer::from(-5);
let error: TryFromIntegerError = match u32::try_from(&i) {
    Ok(_) => unreachable!(),
    Err(error) => error,
};
println!("Error: {}", error);
