gpu_buffer_handle() [1/2]

MAYAFLUX_API Portal::Graphics::GpuBufferHandle MayaFlux::Buffers::gpu_buffer_handle

(

const std::shared_ptr< VKBuffer > &

buffer

)

View a buffer's primary GPU storage without reading it back.

Parameters

buffer

Buffer to view; null yields an empty handle.

Returns

Non-owning handle carrying the Vulkan buffer, its host mapping when the memory is host visible, and the buffer's size in bytes. The caller must keep buffer alive while using it.
