Implementations

impl BoxedMontyParams

pub fn new(modulus: Odd<BoxedUint>) -> Self

Instantiates a new set of BoxedMontyParams representing the given modulus.

TODO(tarcieri): DRY out with MontyParams::new?

pub fn new_vartime(modulus: Odd<BoxedUint>) -> Self

Instantiates a new set of BoxedMontyParams representing the given modulus. This version operates in variable-time with respect to the modulus.

TODO(tarcieri): DRY out with MontyParams::new_vartime?

pub fn modulus(&self) -> &Odd<BoxedUint>

Modulus value.

pub fn bits_precision(&self) -> u32

Bits of precision in the modulus.

pub(crate) fn r2(&self) -> &BoxedUint

pub(crate) fn one(&self) -> &BoxedUint

pub(crate) fn mod_inv(&self) -> U64

pub(crate) fn mod_neg_inv(&self) -> Limb

pub(crate) fn mod_leading_zeros(&self) -> u32

impl BoxedMontyParams

fn inverter(&self) -> BoxedSafeGcdInverter

Compute the inverter for these params.

Trait Implementations

impl AsRef<MontyParams<BoxedUint>> for BoxedMontyParams

fn as_ref(&self) -> &MontyParams<BoxedUint>

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for BoxedMontyParams

fn clone(&self) -> BoxedMontyParams

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl CtAssign for BoxedMontyParams

fn ct_assign(&mut self, other: &Self, choice: Choice)

Conditionally assign src to self if choice is Choice::TRUE.

impl CtEq for BoxedMontyParams

fn ct_eq(&self, other: &Self) -> Choice

Determine if self is equal to other in constant-time.

fn ct_ne(&self, other: &Rhs) -> Choice

Determine if self is NOT equal to other in constant-time.

impl CtEqSlice for BoxedMontyParams

fn ct_eq_slice(a: &[Self], b: &[Self]) -> Choice

Determine if a is equal to b in constant-time.

fn ct_ne_slice(a: &[Self], b: &[Self]) -> Choice

Determine if a is NOT equal to b in constant-time.

impl CtSelect for BoxedMontyParams

fn ct_select(&self, other: &Self, choice: Choice) -> Self

Select between self and other based on choice, returning a copy of the value.

fn ct_swap(&mut self, other: &mut Self, choice: Choice)

Conditionally swap self and other if choice is Choice::TRUE.

impl Debug for BoxedMontyParams

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

Formats the value using the given formatter.

impl<'a> From<&'a BoxedMontyParams> for BoxedMontyMultiplier<'a>

fn from(params: &'a BoxedMontyParams) -> BoxedMontyMultiplier<'a>

Converts to this type from the input type.

impl<const LIMBS: usize> From<&MontyParams<Uint<LIMBS>>> for BoxedMontyParams

fn from(params: &FixedMontyParams<LIMBS>) -> Self

Converts to this type from the input type.

impl From<MontyParams<BoxedUint>> for BoxedMontyParams

fn from(params: MontyParams<BoxedUint>) -> Self

Converts to this type from the input type.

impl<const LIMBS: usize> From<MontyParams<Uint<LIMBS>>> for BoxedMontyParams

fn from(params: FixedMontyParams<LIMBS>) -> Self

impl PartialEq for BoxedMontyParams

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