Expand description

§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§

source

const ALL: Self

The literal !0.

Provided Associated Constants§

source

const INDX: u8 = _

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

source

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§

source§

impl BitRegister for u8

source§

const ALL: Self = 255u8

source§

impl BitRegister for u16

source§

const ALL: Self = 65_535u16

source§

impl BitRegister for u32

source§

const ALL: Self = 4_294_967_295u32

source§

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.
