#include <nda/concepts.hpp>

Detailed Description

Check if a given type satisfies the allocator concept.

Allocators are used to reserve and free memory. Depending on their address space, the memory can either be allocated on the Host (CPU), on the Device (GPU) or on unified memory (see nda::mem::AddressSpace).

Note: The named C++ Allocator requirements of the standard library are different.

Template Parameters

A	Type to check.
