Module arithmetic

This module provides common utilities, traits and structures for group and field arithmetic.

This module is temporary, and the extension traits defined here are expected to be upstreamed into the ff and group crates after some refactoring.

Structs

• Coordinates
  The affine coordinates of a point on an elliptic curve.

Traits

• CurveAffine
  This trait is the affine counterpart to Curve and is used for serialization, storage in memory, and inspection of $x$ and $y$ coordinates.
• CurveExt
  This trait is a common interface for dealing with elements of an elliptic curve group in a “projective” form, where that arithmetic is usually more efficient.
