mju-bits

#[no_std] implementation of typed bitfield access for u8, u16, u32, u64 and usize.

Usage

``` use mju_bits::*;

struct RegisterMarker; type Register = Storage; type RegisterAll = BitField; type RegisterFieldA = BitField; type RegisterFieldB = BitField;

let mut reg = Register::new(); reg.set::(0x56); reg.set::(0x1234); assert_eq!(reg.get::(), 0x00123456); ```

The Storage type ensures that a field may only be used with its corresponding storage.

For example, this won't compile:

```compilefail use mju_bits::*;

struct FooMarker; type Foo = Storage; type FooField = BitField;

struct BarMarker; type Bar = Storage;

let bar = Bar::new();

// Compiler error: FooField can not be used with Bar storage. bar.get::(); ```

Roadmap

• BitFields spanning multiple primitive types
• Iterable sequences of BitFields, supporting functional protocol definition
• Implementation compatible with generic consts on nightly
• Improve types so larger bitfields can be supported - 128-bit fields break typenum
• Others?

Changelog

• 0.3.0 - Removal of B0..B63 aliases to avoid confusion with typenum::B0 and typenum::B1
• 0.2.0 - Documentation and cleanup
• 0.1.0 - Initial release
