std::basic_string_view<CharT,Traits>::find: std::basic_string_view<CharT,Traits>::find

NAME

std::basic_string_view<CharT,Traits>::find - std::basic_string_view<CharT,Traits>::find

Synopsis

constexpr size_type find(basic_string_view v, size_type pos = 0) const noexcept; (1) (since C++17)
constexpr size_type find(CharT ch, size_type pos = 0) const noexcept; (2) (since C++17)
constexpr size_type find(const CharT* s, size_type pos, size_type count) const; (3) (since C++17)
constexpr size_type find(const CharT* s, size_type pos = 0) const; (4) (since C++17)

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(std::addressof(ch), 1), pos).
3) Equivalent to find(basic_string_view(s, count), pos).
4) Equivalent to find(basic_string_view(s), pos).

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

Return value

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

Complexity

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