.. _sprout-string-char_traits-eq: ############################################################################### eq ############################################################################### Interface ======================================== .. sourcecode:: c++ static SPROUT_CONSTEXPR bool eq(char_type c1, char_type c2) SPROUT_NOEXCEPT; Effects ======================================== | Equivalent to ``std::char_traits::eq(c1, c2)``. Examples ======================================== .. sourcecode:: c++ #include using namespace sprout; SPROUT_STATIC_CONSTEXPR char x = 'H'; SPROUT_STATIC_CONSTEXPR char y = 'H'; SPROUT_STATIC_CONSTEXPR auto result = char_traits::eq(x, y); static_assert(result, "x is equal to y."); Complexity ======================================== | constant. | Recursive function invocations in *O(1)* (constant) depth.
