Struct U512

#[repr(C)]
pub struct U512(pub [u64; 8]);

512-bit, stack allocated biginteger for use in extension field serialization and scalar interpretation.

Tuple Fields

0: [u64; 8]

Implementations

impl U512

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

Multiplies c1 by modulo, adds c0.

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 copy 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 Decodable for U512

fn decode<S: Decoder>(s: &mut S) -> Result<U512, S::Error>

Deserialize a value using a Decoder.

impl Encodable for U512

fn encode<S: Encoder>(&self, s: &mut S) -> Result<(), S::Error>

Serialize a value using an Encoder.

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.
