Struct ExtendedUint 

pub(crate) struct ExtendedUint<const LIMBS: usize, const EXTENSION_LIMBS: usize>(Uint<LIMBS>, Uint<EXTENSION_LIMBS>);

Tuple Fields

0: Uint<LIMBS>

1: Uint<EXTENSION_LIMBS>

Implementations

impl<const LIMBS: usize, const EXTRA: usize> ExtendedUint<LIMBS, EXTRA>

pub const fn from_product(lhs: Uint<LIMBS>, rhs: Uint<EXTRA>) -> Self

Construct an ExtendedUint from the product of a Uint<LIMBS> and an Uint<EXTRA>.

Assumes the top bit of the product is not set.

pub const fn wrapping_mul<const RHS_LIMBS: usize>( &self, rhs: &Uint<RHS_LIMBS>, ) -> Self

Wrapping multiply self with rhs

pub const fn as_extended_int(&self) -> ExtendedInt<LIMBS, EXTRA>

Interpret self as an ExtendedInt

pub const fn is_zero(&self) -> Choice

Whether this form is Self::ZERO.

pub const fn checked_drop_extension(&self) -> CtOption<Uint<LIMBS>>

Drop the extension.

pub const fn wrapping_neg(&self) -> Self

Construction the binary negation of self, i.e., map self to !self + 1.

Note: maps 0 to itself.

pub const fn wrapping_neg_if(&self, negate: Choice) -> Self

Negate self if negate is truthy. Otherwise returns self.

pub const fn bounded_shr<const UPPER_BOUND: u32>(&self, shift: u32) -> Self

Shift self right by shift bits.

Panics

• if shift ≥ UPPER_BOUND.

pub const fn shr_vartime(&self, shift: u32) -> Self

Shift self right by shift bits.

Panics

• if shift ≥ Uint::<EXTRA>::BITS.
