std::experi...ind_first_of(3)

okay bestie, welcome to the C++ Standard Libary manual — specifically the std::experi...ind_first_of(3) page. The title is literally truncated like that in the header, and honestly? iconic chaos 💅.

🌸 NAME 🌸

std::experimental::basic_string_view::find_first_of — std::experimental::basic_string_view::find_first_of. Yes, it says the same thing twice, and I respect the commitment 🫶.

✨ Synopsis ✨

Here's the synopsis, overload numbers and (library fundamentals TS) notes and all:

          constexpr size_type find_first_of(basic_string_view v,     (1)
       (library fundamentals
          size_type pos = 0) const noexcept;                             TS)
          constexpr size_type find_first_of(CharT c, size_type pos = (2)
       (library fundamentals
          0) const noexcept;                                             TS)
          constexpr size_type find_first_of(const CharT* s,          (3)
       (library fundamentals
          size_type pos, size_type count) const;                         TS)
          constexpr size_type find_first_of(const CharT* s,          (4)
       (library fundamentals
          size_type pos = 0) const;                                      TS)

Finds the first character equal to any of the characters in the given character sequence.

1. Finds the first occurence of any of the characters of v in this view, starting at position pos. (Yes, occurence is spelled that way on the page — not me 😭)
2. Equivalent to find_first_of(basic_string_view(&c, 1), pos).
3. Equivalent to find_first_of(basic_string_view(s, count), pos).
4. Equivalent to find_first_of(basic_string_view(s), pos).

🎀 Parameters 🎀

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

💖 Return value 💖

Position of the first occurrence of any character of the substring, or npos if no such character is found.

🔥 Complexity 🔥

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