//! 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`] and [`scalar_mul`] documentation for more information.
//!
//! When the vector backend is enabled, the field and scalar
//! implementations are still used for non-vectorized operations.
