Struct DeviceState 

pub struct DeviceState {
    pub kind: String,
    pub id: String,
    pub mmio_slot: u32,
    pub blob: Vec<u8>,
}

One device’s saved state — config + virtqueue cursors.

Devices serialise their own state into bitcode-friendly shapes; the snapshot crate keeps the outer BTreeMap<DeviceKey, DeviceState> so the order is stable across save/restore (per virtio-MMIO slot). The inner blob is opaque.

Fields

kind: String

Device-class name ("virtio-block", "virtio-net", …).

id: String

Identifier the API surface uses (e.g. drive_id, iface_id).

mmio_slot: u32

virtio-MMIO slot index this device occupied.

blob: Vec<u8>

Opaque per-device state — bitcode bytes the device emits.

Trait Implementations

impl Clone for DeviceState

fn clone(&self) -> DeviceState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DeviceState

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DeviceState

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for DeviceState

fn eq(&self, other: &DeviceState) -> 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 Serialize for DeviceState

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for DeviceState

impl StructuralPartialEq for DeviceState
