Expand description

The interface for a generic field.

Required methods

Returns the characteristic of the field.

Returns self + self.

Doubles self in place.

Returns self * self.

Squares self in place.

Computes the multiplicative inverse of self if self is nonzero.

Exponentiates this element by a power of the base prime modulus via the Frobenius automorphism.

Returns a field element with an extra sign bit used for group parsing if the set of bytes forms a valid field element, otherwise returns None. This function is primarily intended for sampling random field elements from a hash-function or RNG output.

Provided methods

Exponentiates this element by a number represented with u64 limbs, least significant limb first.

Returns a field element if the set of bytes forms a valid field element, otherwise returns None. This function is primarily intended for sampling random field elements from a hash-function or RNG output.
