Struct MicrovmState 

pub struct MicrovmState {
    pub vm_info: VmInfo,
    pub vcpu_states: Vec<VcpuState>,
    pub device_states: DeviceStates,
    pub gic_state: GicState,
    pub mmds_state: Option<MmdsState>,
}

The snapshot state blob — the data field of crate::envelope::Snapshot.

Pin per 10-data-model.md § 5.

Fields

vm_info: VmInfo

Top-level VM info.

vcpu_states: Vec<VcpuState>

One per vCPU.

device_states: DeviceStates

Per-device state.

gic_state: GicState

Opaque GIC blob.

mmds_state: Option<MmdsState>

MMDS state if MMDS was enabled.

Implementations

impl MicrovmState

pub fn verify_compatible(&self) -> Result<(), SnapshotError>

Squib-incompat sanity check — surfaces SnapshotError::Incompatible when the loaded state could not have come from a squib-shaped VMM.

Used by the loader after a successful magic + CRC + version check to give --describe-snapshot a clean rejection of e.g. KVM-produced state files that happen to deserialise structurally (D10).

Errors

SnapshotError::Incompatible if any structural invariant is violated.

Trait Implementations

impl Clone for MicrovmState

fn clone(&self) -> MicrovmState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MicrovmState

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

Formats the value using the given formatter.

impl Default for MicrovmState

fn default() -> MicrovmState

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for MicrovmState

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for MicrovmState

fn eq(&self, other: &MicrovmState) -> 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 MicrovmState

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
