:mrdocs:

This `struct` template provides a specialization of the `allocator_traits` class template for `bsl::polymorphic_allocator`. This specialization is not strictly necessary, but its presence speeds up compilation by bypassing a significant amount of metaprogramming.

== Synopsis

Declared in `<bslma_polymorphicallocator.h>`
