constexpr basic_string_view substr(size_type pos = 0, size_type n = npos) const;
constexpr basic_string_view subview(size_type pos = 0, size_type n = npos) const;

Throws: out_of_range if pos > size().

constexpr int compare(basic_string_view str) const noexcept;

Complexity:

O (rlen) .

constexpr int compare(size_type pos1, size_type n1, basic_string_view str) const;

Effects: Equivalent to: return substr(pos1, n1).compare(str);

constexpr int compare(size_type pos1, size_type n1, basic_string_view str,
                      size_type pos2, size_type n2) const;

Effects: Equivalent to: return substr(pos1, n1).compare(str.substr(pos2, n2));

🔗

constexpr int compare(const charT* s) const;

Effects: Equivalent to: return compare(basic_string_view(s));

🔗

Effects: Equivalent to: return !empty() && traits::eq(front(), x);

🔗

constexpr bool starts_with(const charT* x) const;

Effects: Equivalent to: return starts_with(basic_string_view(x));

🔗
