Source of a VmMemoryRequest::RegisterMemory mapping.

Variants

SharedMemory(SharedMemory)

Register shared memory represented by the given descriptor. On Windows, descriptor MUST be a mapping handle.

Descriptor

Fields

descriptor: SafeDescriptor

File descriptor to map.

offset: u64

Offset within the file in bytes.

size: u64

Size of the mapping in bytes.

Register a file mapping from the given descriptor.

Vulkan

Fields

descriptor: SafeDescriptor

handle_type: u32

memory_idx: u32

device_uuid: [u8; 16]

driver_uuid: [u8; 16]

size: u64

Register memory mapped by Vulkano.

ExternalMapping

Fields

ptr: u64

size: u64

Register the current rutabaga external mapping.
