#[repr(C)]
pub union pw_map_item {
    pub next: usize,
    pub data: *mut c_void,
}
Expand description

\private An entry in the map. This is used internally only. Each element in the backing pw_array is a union pw_map_item. For real items, the data pointer points to the item. If an element has been removed, pw_map->free_list is the index of the most recently removed item. That item contains the index of the next removed item until item->next is SPA_ID_INVALID.

The free list is prepended only, the last item to be removed will be the first item to get re-used on the next insert.
