+# allocate_unique: Creating unique_ptr
+:toc:
+:toc-title:
+:idprefix: allocate_unique_
+
+## Description
+
+The `allocate_unique` family of function templates provide convenient and safe
+ways to obtain a `std::unique_ptr` that manages a new object created using an
+allocator.
+
+## Rationale
+
+The {cpp}14 standard introduced `std::make_unique` which used operator `new` to
+create new objects. However, there is no convenient facility in the standard
+library to use an allocator for the creation of the objects managed by
+`std::unique_ptr`. Users writing allocator aware code have often requested an
+`allocate_unique` factory function. This function is to `std::unique_ptr` what
+`std::allocate_shared` is to `std::shared_ptr`.
+
+## Synopsis
+
+`allocate_unique` is defined in `<boost/smart_ptr/allocate_unique.hpp>`.
+
+[subs=+quotes]
+```
+namespace boost {
+  template<class T, class A>
+  class alloc_deleter;
+
+  template<class T, class A>
+  using alloc_noinit_deleter = alloc_deleter<T, noinit_adaptor<A>>;
+
+  `// T is not an array`
+  template<class T, class A, class... Args>
+    std::unique_ptr<T, alloc_deleter<T, A>>
+      allocate_unique(const A& a, Args&&... args);
+
+  `// T is not an array`
+  template<class T, class A>
+    std::unique_ptr<T, alloc_deleter<T, A>>
+      allocate_unique(const A& a, type_identity_t<T>&& v);
+
+  `// T is an array of unknown bounds`
+  template<class T, class A>
+    std::unique_ptr<T, alloc_deleter<T, A>>
+      allocate_unique(const A& a, std::size_t n);
+
+  `// T is an array of known bounds`
+  template<class T, class A>
+    std::unique_ptr<remove_extent_t<T>[], alloc_deleter<T, A>>
+      allocate_unique(const A& a);
+
+  `// T is an array of unknown bounds`
+  template<class T, class A>
+    std::unique_ptr<T, alloc_deleter<T, A>>
+      allocate_unique(const A& a, std::size_t n, const remove_extent_t<T>& v);
+
+  `// T is an array of known bounds`
+  template<class T, class A>
+    std::unique_ptr<remove_extent_t<T>[], alloc_deleter<T, A>>
+      allocate_unique(const A& a, const remove_extent_t<T>& v);
+
+  `// T is not an array`
+  template<class T, class A>
+    std::unique_ptr<T, alloc_noinit_deleter<T, A>>
+      allocate_unique_noinit(const A& a);
+
+  `// T is an array of unknown bounds`
+  template<class T, class A>
+    std::unique_ptr<T, alloc_noinit_deleter<T, A>>
+      allocate_unique_noinit(const A& a, std::size_t n);
+
+  `// T is an array of known bounds`
+  template<class T, class A>
+    std::unique_ptr<remove_extent_t<T>[], alloc_noinit_deleter<T, A>>
+      allocate_unique_noinit(const A& a);
+}
+```
+
+## Common Requirements
+
+The common requirements that apply to all `allocate_unique` and
+`allocate_unique_noinit` overloads, unless specified otherwise, are described
+below.
+
+Requires:: `A` shall be an _allocator_. The copy constructor and destructor
+of `A` shall not throw exceptions.
+
+Effects:: Allocates memory for an object of type `T` or `n` objects of `U`
+(if `T` is an array type of the form `U[]` and  `n` is determined by
+arguments, as specified by the concrete overload). The object is initialized
+from arguments as specified by the concrete overload. Uses a rebound copy of
+`a` (for an unspecified `value_type`) to allocate memory. If an exception is
+thrown, the functions have no effect.
+
+Returns:: A `std::unique_ptr` instance that stores and owns the address of the
+newly constructed object.
+
+Postconditions:: `r.get() != 0`, where `r` is the return value.
+
+Throws:: An exception thrown from `A::allocate`, or from the initialization of
+the object.
+
+Remarks::
+* When an object of an array type is specified to be initialized to a value of
+the same type `v`, this shall be interpreted to mean that each array element
+of the object is initialized to the corresponding element from `v`.
+* When an object of an array type is specified to be value-initialized, this
+shall be interpreted to mean that each array element of the object is
+value-initialized.
+* When a (sub)object of non-array type `U` is specified to be initialized to a
+value `v`, or constructed from `args\...`, `allocate_unique` shall perform this
+initialization via the expression
+`std::allocator_traits<A2>::construct(a2, p, expr)` (where `_expr_` is `v` or
+`std::forward<Args>(args)\...)` respectively), `p` points to storage suitable
+to hold an object of type `U`, and `a2` of type `A2` is a potentially rebound
+copy of `a`.
+* When a (sub)object of non-array type `U` is specified to be
+default-initialized, `allocate_unique_noinit` shall perform this initialization
+via the expression `::new(p) U`, where `p` has type `void*` and points to
+storage suitable to hold an object of type `U`.
+* When a (sub)object of non-array type `U` is specified to be
+value-initialized, `allocate_unique` shall perform this initialization via the
+expression `std::allocator_traits<A2>::construct(a2, p)`, where `p` points to
+storage suitable to hold an object of type `U` and `a2` of type `A2` is a
+potentially rebound copy of `a`.
+* Array elements are initialized in ascending order of their addresses.
+* When the lifetime of the object managed by the return value ends, or when the
+initialization of an array element throws an exception, the initialized
+elements should be destroyed in the reverse order of their construction.
