Struct classygroup::gmp_classgroup::GmpClassGroup

pub struct GmpClassGroup { /* fields omitted */ }

Methods

impl GmpClassGroup

pub fn into_raw(self) -> (Mpz, Mpz)

pub fn with_context<T, U>(cb: T) -> U where
    T: FnOnce(&mut Ctx) -> U, 

Call cb with a mutable reference to the context of type Ctx.

The reference cannot escape the closure and cannot be sent across threads.

Panics

Panics if called recursively. This library guarantees that it will never call this function from any function that takes a parameter of type &mut Ctx.

Trait Implementations

impl ClassGroup for GmpClassGroup

type BigNum = Mpz

fn normalize(&mut self)

Normalize self.

Panics

Panics if called within a call to Self::with_context.

fn inverse(&mut self)

Replaces *self with its inverse.

fn serialize(&self, buf: &mut [u8]) -> Result<(), usize>

Serializes self to a byte array. Returns Err(s) if there is not enough space in the buffer.

fn from_bytes(bytearray: &[u8], discriminant: Self::BigNum) -> Self

Unmarshals a Self from a byte array and discriminant.

fn from_ab_discriminant(
    a: Self::BigNum,
    b: Self::BigNum,
    discriminant: Self::BigNum
) -> Self

Produces a Self from a, b, and a discriminant.

fn discriminant(&self) -> &Self::BigNum

Returns the discriminant of self.

fn size_in_bits(num: &Self::BigNum) -> usize

The length of num in bits

fn reduce(&mut self)

Reduce self.

Panics

Panics if called within a call to Self::with_context.

fn deserialize(buf: &[u8], discriminant: Self::BigNum) -> Self

Deserialization

fn square(&mut self)

Square self.ClassGroupPartial

Panics

Panics if called within the scope of a call to with_context.

fn unsigned_deserialize_bignum(buf: &[u8]) -> Self::BigNum

Deserializes a bignum from raw bytes. The bytes must be interpreted as a big-endian unsigned integer.
