//! 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.
