Concept definition

template<typename C, std::size_t N>
concept Aleph::CA::Coord =  std::regular<C> and requires(C c, std::size_t i) {
  { c[i] } -> std::convertible_to<ca_index_t>;
  { C{}.size() } -> std::convertible_to<std::size_t>;
} and (std::tuple_size<C>::value == N)

Detailed Description

A coordinate type with N integral components.

The CA module manipulates coordinates as fixed-size random-access containers (std::array<index_t, N> is the canonical choice). A coordinate must expose operator[] and a compile-time size().

Template Parameters

C	coordinate type.
N	expected dimension.
