Crate mju_bits

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

Usage:

use typenum::*;
use mju_bits::*;

struct RegisterMarker;
type Register = Storage<RegisterMarker, u32>;
type RegisterAll = BitField<Register, U0, U31>;
type RegisterFieldA = BitField<Register, U0, U7>;
type RegisterFieldB = BitField<Register, U8, U24>;

let mut reg = Register::new();
reg.set::<RegisterFieldA>(0x56);
reg.set::<RegisterFieldB>(0x1234);
assert_eq!(reg.get::<RegisterAll>(), 0x00123456);

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

For example, this won't compile:

use mju_bits::*;

struct FooMarker;
type Foo = Storage<FooMarker, u8>;
type FooField = BitField<Foo, U0, U1>;

struct BarMarker;
type Bar = Storage<BarMarker, u8>;

let bar = Bar::new();
bar.get::<FooField>();
