std::basic_...x::operator=(3)

💖 std::basic_...x::operator=(3) 💖

okay so bestie, welcome to the C++ Standard Libary manual page for std::basic_regex::operator= 💅 yes, that's the manual name, spelled Libary right on the page, and we are keeping the icon exactly as found 🎀

🌸 NAME 🌸

std::basic_regex::operator= - std::basic_regex::operator=

It's literally the assignment operator for std::basic_regex. slay.

✨ Synopsis ✨

Defined in header <regex>.

basic_regex& operator=( const basic_regex& other );
(1) (since C++11)
basic_regex& operator=( basic_regex&& other ) noexcept;
(2) (since C++11)
basic_regex& operator=( const CharT* ptr );
(3) (since C++11)
basic_regex& operator=( std::initializer_list<CharT> il );
(4) (since C++11)
template< class ST, class SA >
(5) (since C++11)
basic_regex& operator=( const std::basic_string<CharT,ST,SA>& p );

Assigns the contents. Here's the overload-by-overload tea 🫖✨

1. Copy assignment operator. Assigns the contents of other. Equivalent to assign(other);.
2. Move assignment operator. Assigns the contents of other using move semantics. After the operation, other is in a valid, but unspecified state. Equivalent to assign(other);.
3. Assigns a null-terminated character string pointed to by ptr. Equivalent to assign(ptr);.
4. Assigns characters contained in initializer list il. Equivalent to assign(il);.
5. Assigns the contents of the string p. Equivalent to assign(p);.

🎀 Parameters 🎀

• other — another regex object.
• ptr — pointer to a null-terminated character string.
• il — initializer list containing characters to assign.
• p — string containing characters to assign.

🌈 Return value 🌈

*this — that's the whole return value, no cap 💅

🔥 Exceptions 🔥

• 1) — may throw implementation-defined exceptions.
• 3-5) — std::regex_error if the supplied regular expression is not valid. The object is not modified in that case.

bestie, if the regex is invalid you get std::regex_error, and the object stays unmodified — no sneaky half-assignment energy 💀

• assign — assigns the contents (public member function).
