Enum ExternalBufferMemory

pub enum ExternalBufferMemory {
    OpaqueFd(Fd),
    DmaBuf(Fd),
    HostAllocation(Ptr),
    HostMappedForeignMemory(Ptr),
}

Representation of an external memory for buffer creation.

Variants

OpaqueFd(Fd)

This is supported on Unix only. Same as ExternalMemoryTypeFlags::OPAQUE_FD while holding a Fd.

DmaBuf(Fd)

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.
