lib.rs:

This library implements a twisted Edwards curve whose base field is the scalar field of the curve BLS12-381. This allows defining cryptographic primitives that use elliptic curves over the scalar field of the latter curve. This curve was generated by Sean Bowe, and is also known as Jubjub.
