castErgonomic, checked cast functions for primitive types
extern crate cast; // `u8` and `u16` are checked cast functions, use them to cast from any numeric // primitive to `u8`/`u16` respectively use cast::{u8, u16, Error}; // Infallible operations, like integer promotion, are equivalent to a normal // cast with `as` assert_eq!(u16(0u8), 0u16); // Everything else will return a `Result` depending on the success of the // operation assert_eq!(u8(0u16), Ok(0u8)); assert_eq!(u8(256u16), Err(Error::Overflow)); assert_eq!(u8(-1i8), Err(Error::Underflow)); assert_eq!(u8(1. / 0.), Err(Error::Infinite)); assert_eq!(u8(0. / 0.), Err(Error::NaN));
