Detailed Description

Custom memory allocators.

This module contains custom memory allocators and allocator utilities used by various other modules.

The following are available as base classes:

• nngn::allocator_base provides default implementations of basic operations.
• nngn::stateless_allocator is a base class for allocators which have no state and should all be considered equal.
• nngn::stateful_allocator is a base class for allocators with state that should never be considered equal.

The following allocators are implemented:

• nngn::reallocator is a realloc(3)-based allocator (thus only useable for trivial types) which supports reallocation.
• nngn::tagging_allocator transparently adds a header to every allocated object, similar to common malloc(3) implementations.
• nngn::tracking_allocator keeps an account of the amount of memory it allocates and deallocates.

In addition, the following helpers are available:

• nngn::alloc_block is a simple type which can be used with some of the above or independently to allocate storage for a type and an associated header.
