//! This library implements the BLS12_377 curve generated in [\[BCGMMW20, “Zexe”\]](https://eprint.iacr.org/2018/962).
//! The name denotes that it is a Barreto--Lynn--Scott curve of embedding degree 12,
//! defined over a 377-bit (prime) field. The main feature of this curve is that
//! both the scalar field and the base field are highly 2-adic.
//! (This is in contrast to the BLS12_381 curve for which only the scalar field is highly 2-adic.)
//!
//!
//! Curve information:
//! * Base field: q = 258664426012969094010652733694893533536393512754914660539884262666720468348340822774968888139573360124440321458177
//! * Scalar field: r = 8444461749428370424248824938781546531375899335154063827935233455917409239041
//! * valuation(q - 1, 2) = 46
//! * valuation(r - 1, 2) = 47
//! * G1 curve equation: y^2 = x^3 + 1
//! * G2 curve equation: y^2 = x^3 + B, where
//!    * B = Fq2(0, 155198655607781456406391640216936120121836107652948796323930557600032281009004493664981332883744016074664192874906)
