Detailed Description

Utility to convert an initializer_list into an array, potentially transforming the initializer_list in the process.

Function Documentation

make_array()

template<class T , std::size_t N, class Fn >
requires std::is_invocable_r_v<T, Fn, std::size_t>

constexpr std::array< T, N > sequoia::utilities::make_array ( Fn  f )

constexpr

Generates an array of size N, formed by applying the function, f, to the indices generated by std::make_index_sequence<N>

to_array()

template<class T , std::size_t N, class Fn = std::identity>
requires std::is_invocable_r_v<T, Fn, T>

constexpr std::array< T, N > sequoia::utilities::to_array ( std::span< const T, N >  data, Fn  f = {}  )

constexpr

Generates an array of size N, formed by applying the function, f, to the elements of the span.
