0: [u128; 4]

Implementations

impl U512

pub fn new(c1: &U256, c0: &U256, modulo: &U256) -> U512

Multiplies c1 by modulo, adds c0.

pub fn from_slice(s: &[u8]) -> Result<U512, Error>

pub fn random<R: Rng>(rng: &mut R) -> U512

Get a random U512

pub fn get_bit(&self, n: usize) -> Option<bool>

pub fn divrem(&self, modulo: &U256) -> (Option<U256>, U256)

Divides self by modulo, returning remainder and, if possible, a quotient smaller than the modulus.

pub fn interpret(buf: &[u8; 64]) -> U512

Trait Implementations

impl Clone for U512

fn clone(&self) -> U512

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for U512

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

Formats the value using the given formatter.

impl From<[u64; 8]> for U512

fn from(d: [u64; 8]) -> Self

Converts to this type from the input type.

impl Ord for U512

fn cmp(&self, other: &U512) -> 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.

impl PartialEq for U512

fn eq(&self, other: &U512) -> 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 PartialOrd for U512

fn partial_cmp(&self, other: &U512) -> 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.
