VM ID

vcpu_count: u32

Number of vCPUs

memory_pages: u64

Total memory pages

region_count: u32

Implementations

impl SnapshotHeader

pub fn is_valid(&self) -> bool

pub fn compute_checksum(&self) -> u64

Compute simple XOR checksum over header fields (excluding checksum itself)

Trait Implementations

impl Clone for SnapshotHeader

fn clone(&self) -> SnapshotHeader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SnapshotHeader

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

Formats the value using the given formatter.

impl Default for SnapshotHeader

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for SnapshotHeader

fn eq(&self, other: &SnapshotHeader) -> 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 Copy for SnapshotHeader

impl Eq for SnapshotHeader
