std::dynamic_extent: std::dynamic_extent

NAME

std::dynamic_extent - std::dynamic_extent

Synopsis


Defined in header <span>
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.

Note


Since std::size_t is an unsigned type, an equivalent definition is:


  inline constexpr std::size_t dynamic_extent = -1;
