Enum Reg 

#[non_exhaustive]
pub enum Reg {
    X(u8),
    SpEl1,
    Pc,
    PState,
}

Reg enum — the registers the trait surface exposes get/set on.

Mirrors the spec in 11-runtime-core.md § 2: X0..X30, SP_EL1, PC, PSTATE.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

X(u8)

General-purpose register Xn where n ∈ 0..=30.

SpEl1

Stack pointer at EL1.

Pc

Program counter.

PState

Processor state register.

Implementations

impl Reg

pub const fn x(index: u8) -> Option<Self>

Build Reg::X with index validation.

Errors

Returns None for indices ≥ 31.

Trait Implementations

impl Clone for Reg

fn clone(&self) -> Reg

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Reg

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for Reg

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Reg

fn eq(&self, other: &Reg) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
