1//! This library implements a twisted Edwards curve whose base field is the
2//! scalar field of the curve BN254. This allows defining cryptographic
3//! primitives that use elliptic curves over the scalar field of the latter curve. This curve is also known as [Baby-Jubjub](https://github.com/barryWhiteHat/baby_jubjub).
