length

Interface

static SPROUT_CONSTEXPR std::size_t length(char_type const* s);

Returns

Equivalent to std::char_traits<Char>::length(s) in constant expression.

Examples

#include <sprout/string.hpp>
using namespace sprout;

SPROUT_STATIC_CONSTEXPR char const* x = "homuhomu";
SPROUT_STATIC_CONSTEXPR auto result = char_traits<char>::length(x);
static_assert(result == 8, "length of x is 8.");

Complexity

linear.

Recursive function invocations in O(logN) (logarithmic) depth.
