[−][src]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>();
