Struct rug::rational::TryFromFloatError
[−]
[src]
pub struct TryFromFloatError { /* fields omitted */ }
An error which can be returned when a checked conversion from a
floating-point number to a Rational
number fails.
Examples
use rug::Rational; use rug::rational::TryFromFloatError; use std::convert::TryFrom; // This is not finite and cannot be converted to Rational. let inf = 1.0f32 / 0.0; let error: TryFromFloatError = match Rational::try_from(inf) { Ok(_) => unreachable!(), Err(error) => error, }; println!("Error: {}", error);
