Trait bitvec::mem::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.

Object Safety

This trait is not object safe.

Implementations on Foreign Types

impl BitRegister for u8

const ALL: Self = 255u8

impl BitRegister for u16

const ALL: Self = 65_535u16

impl BitRegister for u32

const ALL: Self = 4_294_967_295u32

impl BitRegister for u64

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: Self = 18_446_744_073_709_551_615u64

impl BitRegister for usize

const ALL: Self = 18_446_744_073_709_551_615usize
