Struct DynResidueParams

pub struct DynResidueParams<const LIMBS: usize> { /* private fields */ }

The parameters to efficiently go to and from the Montgomery form for an odd modulus provided at runtime.

Implementations

impl<const LIMBS: usize> DynResidueParams<LIMBS>

pub const fn new(modulus: &Uint<LIMBS>) -> Self

Instantiates a new set of ResidueParams representing the given modulus, which must be odd. If modulus is not odd, this function will panic; use new_checked if you want to be able to detect an invalid modulus.

pub fn new_checked(modulus: &Uint<LIMBS>) -> CtOption<Self>

👎Deprecated since 0.5.3: This functionality will be moved to new in a future release.

Instantiates a new set of ResidueParams representing the given modulus if it is odd. Returns a CtOption that is None if the provided modulus is not odd; this is a safer version of new, which can panic.

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

Returns the modulus which was used to initialize these parameters.

pub const fn from_residue_params<P>() -> Self

where P: ResidueParams<LIMBS>,

Create DynResidueParams corresponding to a ResidueParams.

Trait Implementations

impl<const LIMBS: usize> Clone for DynResidueParams<LIMBS>

fn clone(&self) -> DynResidueParams<LIMBS>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<const LIMBS: usize> ConditionallySelectable for DynResidueParams<LIMBS>

fn conditional_select(a: &Self, b: &Self, choice: Choice) -> Self

Select a or b according to choice.

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

Conditionally assign other to self, according to choice.

fn conditional_swap(a: &mut Self, b: &mut Self, choice: Choice)

Conditionally swap self and other if choice == 1; otherwise, reassign both unto themselves.

impl<const LIMBS: usize> ConstantTimeEq for DynResidueParams<LIMBS>

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

Determine if two items are equal.

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

Determine if two items are NOT equal.

impl<const LIMBS: usize> Debug for DynResidueParams<LIMBS>

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

Formats the value using the given formatter.

impl<const LIMBS: usize> PartialEq for DynResidueParams<LIMBS>

fn eq(&self, other: &DynResidueParams<LIMBS>) -> 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.
