std::experi...first_not_of(3)

πŸ“¦ version 2024.07.05, in nixpkgs unstable, opensuse-leap 16.0

okay bestie, this is the std::experi...first_not_of(3) page from the C++ Standard Libary manual β€” yes, that spelling is exactly what the page says, and we are keeping it πŸ’…βœ¨

πŸ’– NAME πŸ’–

std::experimental::basic_string_view::find_first_not_of - std::experimental::basic_string_view::find_first_not_of

✨ Synopsis ✨

So the whole vibe is: find the first character that is not equal to any of the characters in the given character sequence. Here are the four overloads, copied exactly as they appear on the page:

          constexpr size_type
       (library fundamentals
              find_first_not_of(basic_string_view v, size_type pos = (1) TS)
          0) const noexcept;
          constexpr size_type
       (library fundamentals
              find_first_not_of(CharT c, size_type pos = 0) const    (2) TS)
          noexcept;
          constexpr size_type
       (library fundamentals
              find_first_not_of(const CharT* s, size_type pos,       (3) TS)
          size_type count) const;
          constexpr size_type
       (library fundamentals
              find_first_not_of(const CharT* s, size_type pos = 0)   (4) TS)
          const;
  1. Finds the first character not equal to any of the characters of v in this view, starting at position pos.
  2. Equivalent to find_first_not_of(basic_string_view(&c, 1), pos).
  3. Equivalent to find_first_not_of(basic_string_view(s, count), pos).
  4. Equivalent to find_first_not_of(basic_string_view(s), pos).

πŸŽ€ Parameters πŸŽ€

  • v β€” view to search for
  • pos β€” position at which to start the search
  • count β€” length of the string of characters to compare
  • s β€” pointer to a string of characters to compare
  • ch β€” character to compare

🌸 Return value 🌸

It gives you back the position of the first character not equal to any of the characters in the given string, or npos if no such character is found. periodt πŸ’–

πŸ¦‹ Complexity πŸ¦‹

O(size() * v.size()) at worst.
