(C++) std::list

 

std::list is an STL container implemented as a doubly-linked list.

 

std::list is suitable for constant-time random-access insertion and deletion at the cost of linear-time read and write.

Advice

 

• Insertion operators, such as insert() and push_back() are often more efficient on a std::vector than on a std::list [1]
• A std::list is relatively expensive to traverse [2]
• A std::list usually has a four-word-per-element memory overhead [3]
