Function try_from_str 

Source 
pub fn try_from_str<T>(
    val: &str,
) -> Result<Ratio<T>, FromStrErr<<T as FromStr>::Err>>
where
    T: Clone + From<u8> + FromStr + Integer + for<'a> Mul<&'a T, Output = T> + Pow<usize, Output = T>,
Expand description

Converts a string in rational or decimal notation into a Ratio<T>.

§Panics

May panic if T implements arithmetic in a way where panics occur on overflow or underflow.

§Errors

Will return FromStrErr iff val is not a rational number in rational or decimal notation.
