Struct QueueState 

pub struct QueueState {
    pub avail_index: u16,
    pub used_index: u16,
}

Saved progress state for a single virtio queue.

For split queues: avail_index and used_index are plain ring indices. For packed queues: bit 15 of each carries the wrap counter (index | (wrap_counter << 15)), matching the vhost-user wire format.

Fields

avail_index: u16

used_index: u16

Trait Implementations

impl Clone for QueueState

fn clone(&self) -> QueueState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QueueState

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

Formats the value using the given formatter.

impl Default for QueueState

fn default() -> QueueState

Returns the “default value” for a type.

impl DefaultEncoding for QueueState

type Encoding = TableEncoder

The encoding to use for the serialization.

impl DescribeTable for QueueState

const DESCRIPTION: MessageDescription<'static>

The protobuf message description for this type.

impl PartialEq for QueueState

fn eq(&self, other: &QueueState) -> 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.

impl<'encoding, AnyR: 'static> StructDecodeMetadata<'encoding, AnyR> for QueueState

const DECODERS: &'static [ErasedDecoderEntry]

The list of decoder vtables.

impl<AnyR: 'static> StructEncodeMetadata<AnyR> for QueueState

const ENCODERS: &'static [ErasedEncoderEntry]

The list of encoder vtables.

impl StructMetadata for QueueState

const NUMBERS: &'static [u32]

The field numbers for each field.

const OFFSETS: &'static [usize]

The byte offset to each field within the struct.

impl Copy for QueueState

impl Eq for QueueState

impl StructuralPartialEq for QueueState
