Module pasta_curves::arithmetic
source · [−]Expand description
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
allocThe affine coordinates of a point on an elliptic curve.
sqrt-tableTables used for square root computation.
Traits
allocThis trait is the affine counterpart to Curve and is used for
serialization, storage in memory, and inspection of $x$ and $y$ coordinates.
allocThis 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.
This trait is a common interface for dealing with elements of a finite field.
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.
A trait that exposes additional operations related to calculating square roots of prime-order finite fields.
