Struct BigIntFixed 

pub struct BigIntFixed<const L: usize> { /* private fields */ }

Fixed-length BigInt with const-generic limb count.

This type uses a fixed-size array and is suitable for VM registers and fixed-width cryptographic types.

Implementations

impl<const L: usize> BigIntFixed<L>

pub const fn zero() -> Self

Create a new zero BigIntFixed.

pub fn from_u64(value: u64) -> Self

Create a BigIntFixed from a u64 value.

pub fn from_limbs(limbs: &[Limb]) -> Result<Self>

Create a BigIntFixed from a slice of limbs.

If the slice is longer than L, this will truncate. If shorter, the remaining limbs will be zero.

pub fn as_limbs(&self) -> &[Limb; L]

Get a reference to the limb array.

pub fn as_limbs_mut(&mut self) -> &mut [Limb; L]

Get a mutable reference to the limb array.

Trait Implementations

impl<const L: usize> BigIntCore for BigIntFixed<L>

fn limb_count(&self) -> usize

Get the number of limbs.

fn limbs(&self) -> &[Limb]

Get a reference to the limbs.

fn limbs_mut(&mut self) -> &mut [Limb]

Get a mutable reference to the limbs.

fn sign(&self) -> bool

Get the sign bit (false = positive, true = negative).

fn set_sign(&mut self, sign: bool)

Set the sign bit.

fn canonicalize(&mut self) -> Result<()>

Ensure canonical form.

fn is_zero(&self) -> bool

Check if the value is zero.

impl<const L: usize> Clone for BigIntFixed<L>

fn clone(&self) -> BigIntFixed<L>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<const L: usize> Debug for BigIntFixed<L>

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

Formats the value using the given formatter.
