Enum MappingType 

pub enum MappingType {
    Ram,
    Device,
}

The type of memory backing a region or mapping.

Variants

Ram

Guest RAM or similar shareable memory. IOMMU mapping failures are fatal. Exposed via GuestMemorySharing (vhost-user).

Device

Device memory (e.g., a PCI BAR). IOMMU mapping failures are non-fatal — they only affect peer-to-peer DMA to this region. Not exposed via GuestMemorySharing.

Trait Implementations

impl Clone for MappingType

fn clone(&self) -> MappingType

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MappingType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl DefaultEncoding for MappingType

type Encoding = OneofEncoder

The encoding to use for the serialization.

impl Inspect for MappingType

fn inspect(&self, req: Request<'_>)

Inspects the object.

impl<'encoding> OneofDecode<'encoding, Resource> for MappingType

fn read_variant( item: &mut InplaceOption<'_, Self>, n: u32, field: FieldReader<'encoding, '_, Resource>, ) -> Result<()>

Read the specified variant from the reader.

impl OneofEncode<Resource> for MappingType

fn write_variant(self, writer: MessageWriter<'_, '_, Resource>)

Write the variant to the writer.

fn compute_variant_size(&mut self, sizer: MessageSizer<'_>)

Compute the size of the variant.

impl PartialEq for MappingType

fn eq(&self, other: &MappingType) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
