length

Interface

template<typename ConstInputIterator>
static SPROUT_CONSTEXPR std::size_t length(ConstInputIterator s);

Returns

The smallest i such that eq(s[i], char_type()) is true.

Examples

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

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

Complexity

linear.

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