[−][src]Struct rug::rational::ParseRationalError
An error which can be returned when parsing a Rational
number.
See the Rational::parse_radix
method for details on what strings
are accepted.
Examples
use rug::{rational::ParseRationalError, Rational}; // This string is not a rational number. let s = "something completely different (_!_!_)"; let error: ParseRationalError = match Rational::parse_radix(s, 4) { Ok(_) => unreachable!(), Err(error) => error, }; println!("Parse error: {}", error);
