inline constexpr std::size_t dynamic_extent = std::numeric_limits<std::size_t>::max(); | (since C++20) |
std::dynamic_extent is a constant of type std::size_t that is used to differentiate std::span of static and dynamic extent.
Since std::size_t is an unsigned type, an equivalent definition is:
inline constexpr std::size_t dynamic_extent = -1;
