//! Pluggable implementations for different architectures.
//!
//! The backend code is split into two parts: a serial backend,
//! and a vector backend.
//!
//! The [`serial`] backend contains 32- and 64-bit implementations of
//! field arithmetic and scalar arithmetic, as well as implementations
//! of point operations using the mixed-model strategy (passing
//! between different curve models depending on the operation).
//!
//! The [`vector`] backend contains implementations of vectorized
//! field arithmetic, used to implement point operations using a novel
//! implementation strategy derived from parallel formulas of Hisil,
//! Wong, Carter, and Dawson.
//!
//! Because the two strategies give rise to different curve models,
//! it's not possible to reuse exactly the same scalar multiplication
//! code (or to write it generically), so both serial and vector
//! backends contain matching implementations of scalar multiplication
//! algorithms.  These are intended to be selected by a `#[cfg]`-based
//! type alias.
//!
//! The [`vector`] backend is selected by the `simd_backend` cargo
//! feature; it uses the [`serial`] backend for non-vectorized operations.
