constexprvoid swap(std::inplace_vector& lhs, std::inplace_vector& rhs)noexcept(/* see below */); | (since C++26) | |
Specializes thestd::swap algorithm forstd::inplace_vector. Swaps the contents oflhs andrhs. Callslhs.swap(rhs).
Contents |
| lhs, rhs | - | containers whose contents to swap |
Linear in size of the containers.
#include <algorithm>#include <iostream>#include <inplace_vector> int main(){std::inplace_vector<int,4> alice{1,2,3};std::inplace_vector<int,4> bob{7,8,9,10}; auto print=[](constint& n){std::cout<<' '<< n;}; // Print state before swapstd::cout<<"Alice:";std::for_each(alice.begin(), alice.end(), print);std::cout<<"\nBobby:";std::for_each(bob.begin(), bob.end(), print);std::cout<<'\n'; std::cout<<"-- SWAP\n";std::swap(alice, bob); // Print state after swapstd::cout<<"Alice:";std::for_each(alice.begin(), alice.end(), print);std::cout<<"\nBobby:";std::for_each(bob.begin(), bob.end(), print);std::cout<<'\n';}
Output:
Alice: 1 2 3Bobby: 7 8 9 10-- SWAPAlice: 7 8 9 10Bobby: 1 2 3
