Trait BitRegister

pub trait BitRegister: Unsigned + BitOps {
    const ALL: Self;
    const INDX: u8 = _;
    const MASK: u8 = _;
}

Register Descriptions

This trait describes the unsigned integer types that can be manipulated in a target processor’s general-purpose registers. It has no bearing on the processor instructions or registers used to interact with the memory bus, and solely exists to describe integers that can exist on a system.

Required Associated Constants

const ALL: Self

The literal !0.

Provided Associated Constants

const INDX: u8 = _

The number of bits required to store an index in the range 0 .. BITS.

const MASK: u8 = _

A mask over all bits that can be used as an index within the element. This is the value with the least significant INDX-many bits set high.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementations on Foreign Types

impl BitRegister for u8

const ALL: u8 = 255u8

impl BitRegister for u16

const ALL: u16 = 65_535u16

impl BitRegister for u32

const ALL: u32 = 4_294_967_295u32

impl BitRegister for u64

Available on 64-bit only.

u64 can only be used as a register on processors whose word size is at least 64 bits.

This implementation is not present on targets with 32-bit processor words.

const ALL: u64 = 18_446_744_073_709_551_615u64

impl BitRegister for usize

const ALL: usize = 18_446_744_073_709_551_615usize
