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

Finds the first substring equal to the given character sequence.

1) Finds the first occurence of v in this view, starting at position pos.
2) Equivalent to find(basic_string_view(&c, 1), pos).
3) Equivalent to find(basic_string_view(s, count), pos).
4) Equivalent to find(basic_string_view(s), pos).

[edit] Parameters

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


[edit] Return value

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

[edit] Complexity

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