Struct VirtioBlkCountersSnapshot 

pub struct VirtioBlkCountersSnapshot {
    pub reads_completed: u64,
    pub writes_completed: u64,
    pub flushes_completed: u64,
    pub bytes_read: u64,
    pub bytes_written: u64,
    pub throttled_count: u64,
    pub io_errors: u64,
    pub currently_throttled_gauge: u64,
    pub invalid_avail_idx_count: u64,
}

Plain-u64 snapshot of VirtioBlkCounters taken at VM-result construction time. Mirrors every atomic field by name.

Decouples the public-facing crate::vmm::VmResult from the internal atomic-shared writer state — consumers see immutable owned data they can Clone, compare, and round-trip through serde without the Arc<AtomicU64> ceremony. The worker thread continues to bump the atomics via the VirtioBlkCounters record_* mutators; only the result-construction path moves to the snapshot.

Field semantics match the atomic source one-for-one — see VirtioBlkCounters for the cumulative-vs-gauge taxonomy distinguishing each field. The live-gauge field currently_throttled_gauge reflects the gauge state at snapshot time — typically 0 after a clean shutdown, but per the VirtioBlkCounters doc a worker-strand stall during teardown can leave a non-zero residual.

Trait Implementations

impl Clone for VirtioBlkCountersSnapshot

fn clone(&self) -> VirtioBlkCountersSnapshot

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VirtioBlkCountersSnapshot

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

Formats the value using the given formatter.

impl Default for VirtioBlkCountersSnapshot

fn default() -> VirtioBlkCountersSnapshot

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for VirtioBlkCountersSnapshot

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for VirtioBlkCountersSnapshot

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for VirtioBlkCountersSnapshot

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
