Detailed Description

Type traits for backend metadata and capabilities.

This header provides compile-time type traits that describe the capabilities of different backends. These traits can be used for conditional compilation and static assertions to ensure correct usage of backend-specific features.

#include <openpfc/core/memory_traits.hpp>
 
// Check if backend supports host access
if constexpr (pfc::core::backend_traits<pfc::backend::CpuTag>::has_host_access) {
    // Can use operator[]
    buffer[0] = 1.0;
}
 
// Check if backend requires transfers
if constexpr (pfc::core::backend_traits<pfc::backend::CudaTag>::requires_transfer)
{
    // Must use copy_from_host/to_host
    buffer.copy_from_host(host_data);
}
