VIRTIO_F_RING_EVENT_IDX negotiated.

size: u16

The queue size in elements the driver selected.

ready: bool

Indicates if the queue finished with the configuration.

Guest physical address of the available ring.

used_ring: u64

Guest physical address of the used ring.

Trait Implementations

impl Clone for QueueStateSer

fn clone(&self) -> QueueStateSer

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for QueueStateSer

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

Formats the value using the given formatter.

impl Default for QueueStateSer

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for QueueStateSer

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<&QueueState> for QueueStateSer

fn from(state: &QueueState) -> Self

Converts to this type from the input type.

impl From<&QueueStateSer> for QueueState

fn from(state: &QueueStateSer) -> Self

Converts to this type from the input type.

impl PartialEq for QueueStateSer

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for QueueStateSer

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Versionize for QueueStateSer

fn serialize<W: Write>( &self, writer: &mut W, version_map: &VersionMap, app_version: u16 ) -> VersionizeResult<()>

Serializes self to target_verion using the specficifed writer and version_map.

fn deserialize<R: Read>( reader: &mut R, version_map: &VersionMap, app_version: u16 ) -> VersionizeResult<Self>

Returns a new instance of Self by deserializing from source_version using the specficifed reader and version_map.

fn version() -> u16

Returns latest Self version number.

fn type_id() -> TypeId

where Self: 'static,

Returns the Self type id. The returned ID represents a globally unique identifier for a type. It is required by the VersionMap implementation.
