Enum WordVal 

pub enum WordVal {
    W32(Word32),
    W64(Word64),
}

A fixed-width wrapping integer of either supported width — the single runtime carrier for Word32/Word64 across the interpreter, VM, and wire, so the rest of the system matches on one Word value rather than a variant per width. Binary ops require matching widths; a width mismatch is a type error the caller reports (the ops return None).

Variants

W32(Word32)

A 32-bit wrapping value.

W64(Word64)

A 64-bit wrapping value.

Implementations

impl WordVal

pub const fn width(self) -> u32

Bit width, 32 or 64.

pub const fn to_u64(self) -> u64

The value zero-extended to u64 — the canonical scalar form for display, hashing into other contexts, and the wire.

pub const fn from_u64(width: u32, bits: u64) -> Option<Self>

Build a word of the given width from the low bits of bits (32 → truncates to u32).

pub fn add(self, o: Self) -> Option<Self>

Wrapping addition; None on a width mismatch.

pub fn sub(self, o: Self) -> Option<Self>

Wrapping subtraction; None on a width mismatch.

pub fn mul(self, o: Self) -> Option<Self>

Wrapping multiplication; None on a width mismatch.

pub fn bitand(self, o: Self) -> Option<Self>

Bitwise AND; None on a width mismatch.

pub fn bitor(self, o: Self) -> Option<Self>

Bitwise OR; None on a width mismatch.

pub fn bitxor(self, o: Self) -> Option<Self>

Bitwise XOR; None on a width mismatch.

pub const fn not(self) -> Self

Bitwise complement (width-preserving).

pub const fn shl(self, n: u32) -> Self

Logical left shift by n (width-preserving).

pub const fn shr(self, n: u32) -> Self

Logical right shift by n (width-preserving).

pub const fn rotl(self, n: u32) -> Self

Left rotation by n (width-preserving) — the bit-permutation crypto needs.

pub const fn rotr(self, n: u32) -> Self

Right rotation by n (width-preserving).

Trait Implementations

impl Clone for WordVal

fn clone(&self) -> WordVal

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WordVal

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

Formats the value using the given formatter.

impl Display for WordVal

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

A word renders as its unsigned decimal value (no width suffix), so a Word32 holding 5 and an Int 5 print identically — the value is what Show reports.

impl Hash for WordVal

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 WordVal

fn eq(&self, other: &WordVal) -> 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.
