Exceptions
If an exception is thrown (which can be due to Allocator::allocate()
or element copy/move constructor/assignment), this function has no effect (strong exception guarantee).
Example
Run this code
#include <{{{1}}}> #include <iostream> #include <iomanip> int main() { std::{{{1}}}<std::string> numbers; numbers.push_back("abc"); std::string s = "def"; numbers.push_back(std::move(s)); std::cout << "{{{1}}} holds: "; for (auto&& i : numbers) std::cout << std::quoted(i) << ' '; std::cout << "\nMoved-from string holds " << std::quoted(s) << '\n'; }
Output:
{{{1}}} holds: "abc" "def" Moved-from string holds ""
