Merge "Upgrade rust/crates/cast to 0.3.0" am: a860660912 am: b3daea5e9f am: ce06b14f42 am: 0b093da5a5 Original change: https://android-review.googlesource.com/c/platform/external/rust/crates/cast/+/1833320 Change-Id: I6c84ae09a568eaa0a7a77af51a643dbe92727848
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));
