Detailed Description

template<typename Tag>
class donner::gpu::HandleRef< Tag >

Copyable non-owning reference to a Handle, used inside descriptor structs.

Handles are move-only, so descriptors reference them through this identity-only view instead. The device re-validates slot, generation, and device identity when the descriptor is consumed, so a stale or foreign reference fails closed exactly like a stale or foreign handle.

Template Parameters

Tag	Tag type identifying the resource type.

Constructor & Destructor Documentation

HandleRef()

template<typename Tag>

donner::gpu::HandleRef< Tag >::HandleRef ( const Handle< Tag > & handle )

inline

Implicitly references handle.

The reference does not keep the resource alive.

Parameters

handle

Handle to reference.

operator==

template<typename Tag>

bool operator== ( const HandleRef< Tag > & ref, std::nullptr_t  )

friend

Compares against null: true if the reference is null.

Parameters

ref	Reference to test.
