Type-erased and polymorphic allocators
Sampling and searching algorithms
| Defined in header
<experimental/algorithm> | |

| Defined in header
<experimental/functional> | |
| standard C++ library search algorithm implementation (class template) | |
| helper function to create a default_searcher (function template) | |
| Boyer-Moore search algorithm implementation (class template) | |
| helper function to create a boyer_moore_searcher (function template) | |
| Boyer-Moore-Horspool search algorithm implementation (class template) | |

General utilities
| Defined in header
<experimental/utility> | |||
| placeholder type for type erasure, such as in allocators (class) | |||
| Defined in header
<experimental/tuple> | |||
| exposes std::tuple_size as a variable template (variable template) | |||
| calls a function to a tuple of arguments (function template) | |||
Metaprogramming and type traits | |||
| Defined in header
<experimental/type_traits> | |||
| exposes std::is_void as a variable template (variable template) | |||
| exposes std::is_null_pointer as a variable template (variable template) | |||
| |||
| deduce the implied function type of the callable object when called with the given argument types (class template) | |||
