cast

Ergonomic, checked cast functions for primitive types

``` rust 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 asserteq!(u8(0u16), Ok(0u8)); asserteq!(u8(256u16), Err(Error::Overflow)); asserteq!(u8(-1i8), Err(Error::Underflow)); asserteq!(u8(1. / 0.), Err(Error::Infinite)); assert_eq!(u8(0. / 0.), Err(Error::NaN)); ```
