Detailed Description

template<AZStd::size_t Size, AZStd::size_t Alignment>
class AZStd::static_buffer_allocator< Size, Alignment >

This allocator uses aligned_storage to declare a static buffer, which is used for all allocations. This allocator is designed to be used as a temporary allocator on the stack. It just allocates from the buffer never frees anything, until you call reset. It does allow memory leaks, thus allowing containers never to call deallocate, which makes them faster.
