Struct BoxedMontyParams

pub struct BoxedMontyParams { /* private fields */ }

Available on crate feature alloc only.

Parameters to efficiently go to/from the Montgomery form for an odd modulus whose size and value are both chosen at runtime.

Implementations

impl BoxedMontyParams

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

Instantiates a new set of BoxedMontyParams representing the given modulus, which must be odd.

Returns a CtOption that is None if the provided modulus is not odd. 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, which must be odd. This version operates in variable-time with respect to the modulus.

Returns None if the provided modulus is not odd. TODO(tarcieri): DRY out with MontyParams::new?

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

Modulus value.

pub fn bits_precision(&self) -> u32

Bits of precision in the modulus.

pub fn from_const_params<const LIMBS: usize, P: ConstMontyParams<LIMBS>>() -> Self

Create from a set of ConstMontyParams.

Trait Implementations

impl Clone for BoxedMontyParams

fn clone(&self) -> BoxedMontyParams

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BoxedMontyParams

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

Formats the value using the given formatter.

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.

impl PrecomputeInverter for BoxedMontyParams

type Inverter = BoxedMontyFormInverter

Inverter type for integers of this size.

type Output = BoxedMontyForm

Output produced by the inverter.

fn precompute_inverter(&self) -> BoxedMontyFormInverter

Obtain a precomputed inverter for &self as the modulus, using Self::one() as an adjusting parameter.
