Expand description

This represents an element of a group with basic operations that can be performed. This allows an FFT implementation (for example) to operate generically over either a field or elliptic curve group.

Required Associated Types

The group is assumed to be of prime order $p$. Scalar is the associated scalar field of size $p$.

Required Methods

Returns the additive identity of the group.

Adds rhs to this group element.

Subtracts rhs from this group element.

Scales this group element by a scalar.
