constexpr basic_string& assign(const basic_string& str);

Effects: Equivalent to: return *this = str;

constexpr basic_string& assign(basic_string&& str) noexcept(allocator_traits<Allocator>::propagate_on_container_move_assignment::value || allocator_traits<Allocator>::is_always_equal::value);

Effects: Equivalent to: return *this = std::move(str);

constexpr basic_string& assign(const basic_string& str, size_type pos, size_type n = npos);

Effects: Equivalent to:return assign(basic_string_view<charT, traits>(str).substr(pos, n));

template<class T> constexpr basic_string& assign(const T& t);

Constraints:

is_convertible_v<const T&, basic_string_view<charT, traits>> istrue and
is_convertible_v<const T&, const charT*> isfalse.

Effects: Equivalent to:basic_string_view<charT, traits> sv = t;return assign(sv.data(), sv.size());

template<class T> constexpr basic_string& assign(const T& t, size_type pos, size_type n = npos);

Constraints:

is_convertible_v<const T&, basic_string_view<charT, traits>> istrue and
is_convertible_v<const T&, const charT*> isfalse.

Effects: Equivalent to:basic_string_view<charT, traits> sv = t;return assign(sv.substr(pos, n));

constexpr basic_string& assign(const charT* s, size_type n);

Preconditions: [s, s + n) is a valid range.

Effects: Replaces the string controlled by *this with a copy of the range [s, s + n).

constexpr basic_string& assign(const charT* s);

Effects: Equivalent to: return assign(s, traits::length(s));

constexpr basic_string& assign(initializer_list<charT> il);

Effects: Equivalent to: return assign(il.begin(), il.size());

constexpr basic_string& assign(size_type n, charT c);

Effects: Equivalent to:clear(); resize(n, c);return *this;

template<class InputIterator> constexpr basic_string& assign(InputIterator first, InputIterator last);

Constraints: InputIterator is a type that qualifies as an input iterator ([container.reqmts]).

Effects: Equivalent to: return assign(basic_string(first, last, get_allocator()));
