HostMappedForeignMemory(Ptr),
}
Expand description
Representation of an external memory for image creation.
Variants
OpaqueFd(Fd)
This is supported on Unix only. Same as ExternalMemoryTypeFlags::OPAQUE_FD while holding a Fd.
DmaBuf(Fd, Option<DrmFormatImageProperties>)
This is supported on Linux or Android only. Same as ExternalMemoryTypeFlags::DMA_BUF while holding a Fd.
HostAllocation(Ptr)
Same as ExternalMemoryTypeFlags::HOST_ALLOCATION while holding a Ptr.
HostMappedForeignMemory(Ptr)
Same as ExternalMemoryTypeFlags::HOST_MAPPED_FOREIGN_MEMORY while holding a Ptr.
