Struct BigInt 

pub struct BigInt { /* private fields */ }

Signed multiprecision integer used by later public-key helpers.

Implementations

impl BigInt

pub fn zero() -> Self

Construct zero.

pub fn from_parts(sign: Sign, magnitude: BigUint) -> Self

Construct from an explicit sign and magnitude.

pub fn from_biguint(magnitude: BigUint) -> Self

Construct a non-negative signed integer from an unsigned value.

pub fn sign(&self) -> Sign

Return the sign.

pub fn magnitude(&self) -> &BigUint

Return the absolute value.

pub fn negated(&self) -> Self

Negate the integer.

pub fn add_ref(&self, other: &Self) -> Self

Return self + other.

pub fn sub_ref(&self, other: &Self) -> Self

Return self - other.

pub fn mul_biguint_ref(&self, factor: &BigUint) -> Self

Return self * factor for a non-negative factor.

pub fn modulo_positive(&self, modulus: &BigUint) -> BigUint

Reduce modulo a positive modulus and return the least non-negative residue.

Panics

Panics if modulus == 0.

Trait Implementations

impl Clone for BigInt

fn clone(&self) -> BigInt

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BigInt

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

Formats the value using the given formatter.

impl PartialEq for BigInt

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