Struct mariadb_sys::I_P_List

#[repr(C)]
pub struct I_P_List<T, C, I> {
    pub _base: C,
    pub _base_1: I,
    pub m_first: *mut T,
    pub _phantom_0: PhantomData<UnsafeCell<T>>,

}

Intrusive parameterized list.

Unlike I_List does not require its elements to be descendant of ilink class and therefore allows them to participate in several such lists simultaneously.

Unlike List is doubly-linked list and thus supports efficient deletion of element without iterator.

• T () Type of elements which will belong to list.

• B () Class which via its methods specifies which members of T should be used for participating in this list. Here is typical layout of such class:

struct B { static inline T **next_ptr(T *el) { return &el->next; } static inline T ***prev_ptr(T *el) { return &el->prev; } };

• C () Policy class specifying how counting of elements in the list should be done. Instance of this class is also used as a place where information about number of list elements is stored. @sa I_P_List_null_counter, I_P_List_counter

• I () Policy class specifying whether I_P_List should support efficient push_back() operation. Instance of this class is used as place where we store information to support this operation. @sa I_P_List_no_push_back, I_P_List_fast_push_back.
