Numeric casts

This crate provides checked, overflowing and static casts.

What’s new

Version 0.2.0 news (2019-09-10)

• The old *As traits were renamed to [*Cast].
• New more convenient [*As] traits were added.

Quick examples

```rust use az::{Az, OverflowingAs, WrappingAs}; use core::num::Wrapping;

// Panics on overflow with debug_assertions, otherwise wraps assert_eq!(12i32.az::(), 12u32);

// Always wraps let wrapped = 1u32.wrappingneg(); asserteq!((-1).wrappingas::(), wrapped); asserteq!((-1).overflowing_as::(), (wrapped, true));

// Wrapping can also be obtained using Wrapping assert_eq!((-1).az::>().0, wrapped); ```

Conversions from floating-point to integers are also supported. Numbers are rounded towards zero, but the [Round] wrapper can be used to convert floating-point numbers to integers with rounding to the nearest, with ties rounded to even.

```rust use az::{Az, CheckedAs, Round, SaturatingAs}; use core::f32;

asserteq!(15.7.az::(), 15); asserteq!(Round(15.5).az::(), 16); asserteq!(1.5e20.saturatingas::(), i32::maxvalue()); asserteq!(f32::NAN.checked_as::(), None); ```
