比较二个 scoped_allocator_adaptors 。若满足下列条件则二个这种分配器相等:

  • lhs.outer_allocator() == rhs.outer_allocator() ,且
  • sizeof...(InnerAllocs) > 0 ,则 lhs.inner_allocator() == rhs.inner_allocator()

lhs, rhs - 要比较的 scoped_allocator_adaptors

[编辑] 返回值

1)lhsrhs 相等,则返回 true ,否则返回 false
2)lhsrhs 不相等,则返回 true ,否则返回 false
