Detailed Description

template<typename Element, std::size_t NUM_ROUNDS>
struct bb::group_elements::detail::EndomorphismWnaf< Element, NUM_ROUNDS >

Handles the WNAF computation for scalars that are split using an endomorphism, achieved through split_into_endomorphism_scalars. It facilitates efficient computation of elliptic curve point multiplication by optimizing the representation of these scalars.

Template Parameters

Element	The data type of elements in the elliptic curve.
NUM_ROUNDS	The number of computation rounds for WNAF.
