//! This library implements a twisted Edwards curve whose base field is the
//! scalar field of the curve CP6. This allows defining cryptographic primitives
//! that use elliptic curves over the scalar field of the latter curve. This curve was generated as part of the paper [\[BCGMMW20, “Zexe”\]](https://eprint.iacr.org/2018/962).
//!
//! Curve information:
//! * Base field: q = 258664426012969094010652733694893533536393512754914660539884262666720468348340822774968888139573360124440321458177
