constexpr size_type size_bytes() const noexcept; |
(since C++20) | |
Returns the size of the sequence in bytes.
Parameters
(none)
Return value
The size of the sequence in bytes, i.e., size() * sizeof(element_type).
Example
Run this code
#include <cstdint> #include <span> int main() { constexpr static std::int32_t a[]{1, 2, 3, 4, 5}; constexpr static std::span s{a}; static_assert ( sizeof(int32_t) == 4 && std::size(a) == 5 && sizeof a == 20 && s.size() == 5 && s.size_bytes() == 20 ); }
