Struct BigUint 

pub struct BigUint { /* private fields */ }

An unsigned integer of arbitrary size (64-bit limbs, least significant first).

Implementations

impl BigUint

pub fn is_zero(&self) -> bool

Whether the value is zero.

pub fn bits(&self) -> usize

The number of significant bits (0 for zero): ⌊log2 v⌋ + 1.

pub fn mul_small(&self, k: u64) -> BigUint

The product by a machine integer.

pub fn div_small(&self, k: u64) -> (BigUint, u64)

The quotient and the remainder of the division by a machine integer.

Panics

If k is zero.

pub fn add(&self, o: &BigUint) -> BigUint

The sum.

pub fn sub(&self, o: &BigUint) -> BigUint

The difference self - o.

Panics

If o > self.

pub fn from_bits(bits: &[u8]) -> BigUint

The integer whose binary digits are bits, most significant first.

pub fn to_bits(&self, n: usize) -> Vec<u8>

The n lowest binary digits, most significant first.

Trait Implementations

impl Clone for BigUint

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BigUint

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

Formats the value using the given formatter.

impl Default for BigUint

fn default() -> Self

Returns the “default value” for a type.

impl Eq for BigUint

impl From<u64> for BigUint

fn from(v: u64) -> BigUint

Converts to this type from the input type.

impl Ord for BigUint

fn cmp(&self, o: &BigUint) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for BigUint

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl PartialOrd for BigUint

fn partial_cmp(&self, o: &BigUint) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
