//! Serial implementations of field, scalar, point arithmetic.
//!
//! When the vector backend is disabled, the crate uses the
//! mixed-model strategy for implementing point operations and scalar
//! multiplication; see the [`curve_models`](self::curve_models) and
//! [`scalar_mul`](self::scalar_mul) documentation for more
//! information.
//!
//! When the vector backend is enabled, the field and scalar
//! implementations are still used for non-vectorized operations.
//!
//! Note: at this time the `u32` and `u64` backends cannot be built
//! together.
