//! A non-standard allocator used to implement `small_vector`.
//! Users should never use it directly. It is described here
//! for documentation purposes.
//!
//! This allocator inherits from a standard-conforming allocator
//! and forwards member functions to the standard allocator except
//! when internal storage is being used as memory source.
//!
//! This allocator is a "partially_propagable" allocator and
//! defines `is_partially_propagable` as true_type.
//!
//! A partially propagable allocator means that not all storage
//! allocatod by an instance of `small_vector_allocator` can be
//! deallocated by another instance of this type, even if both
//! instances compare equal or an instance is propagated to another
//! one using the copy/move constructor or assignment. The storage that
//! can never be propagated is identified by `storage_is_unpropagable(p)`.
//!
//! `boost::container::vector` supports partially propagable allocators
//! fallbacking to deep copy/swap/move operations when internal storage
//! is being used to store vector elements.
//!
//! `small_vector_allocator` assumes that will be instantiated as
//! `boost::container::vector< T, small_vector_allocator<T, Allocator> >`
//! and internal storage can be obtained downcasting that vector
//! to `small_vector_base<T>`.
