Struct plonk_pallet::BlsScalar[−]

pub struct BlsScalar(pub [u64; 4]);
Expand description

Represents an element of the scalar field $\mathbb{F}_q$ of the BLS12-381 elliptic curve construction.

Tuple Fields

0: [u64; 4]

Implementations

Returns zero, the additive identity.

Returns one, the multiplicative identity.

Checks in ct_time whether a Scalar is equal to zero.

Checks in ct_time whether a Scalar is equal to one.

Returns the internal representation of the Scalar.

Doubles this field element.

Returns the bit representation of the given Scalar as an array of 256 bits represented as u8.

Converts a 512-bit little endian integer into a Scalar by reducing by the modulus.

Converts from an integer represented in little endian into its (congruent) Scalar representation.

Generate a valid Scalar choosen uniformly using user- provided rng.

By rng we mean any Rng that implements: Rng + CryptoRng.

Reduces the scalar and returns it multiplied by the montgomery radix.

Squares this element.

Computes the square root of this element, if it exists.

Exponentiates self by by, where by is a little-endian order integer exponent.

Exponentiates self by by, where by is a little-endian order integer exponent.

This operation is variable time with respect to the exponent. If the exponent is fixed, this operation is effectively constant time.

Computes 2^X where X is a u64 without the need to generate

Computes the multiplicative inverse of this element, failing if the element is zero.

Multiplies rhs by self, returning the result.

Subtracts rhs from self, returning the result.

Adds rhs to self, returning the result.

Negates self.
