Detailed Description

template<typename _Alloc = std::allocator<char>>
class __gnu_pbds::lu_move_to_front_policy< _Alloc >

A list-update policy that unconditionally moves elements to the front of the list. A null type means that each link in a list-based container does not actually need metadata.

Definition at line 58 of file list_update_policy.hpp.
