Struct SnapshotLoadParams

pub struct SnapshotLoadParams {
    pub enable_diff_snapshots: Option<bool>,
    pub mem_file_path: Option<PathBuf>,
    pub mem_backend: Option<MemoryBackend>,
    pub resume_vm: Option<bool>,
    pub snapshot_path: PathBuf,
}

Defines the configuration used for handling snapshot resume. Exactly one of the two mem_* fields must be present in the body of the request.

Fields

enable_diff_snapshots: Option<bool>

Enable support for incremental (diff) snapshots by tracking dirty guest pages.

mem_file_path: Option<PathBuf>

Path to the file that contains the guest memory to be loaded. It is only allowed if mem_backend is not present. This parameter has been deprecated and it will be removed in future Firecracker release. Required: true

mem_backend: Option<MemoryBackend>

Configuration for the backend that handles memory load. If this field

resume_vm: Option<bool>

When set to true, the vm is also resumed if the snapshot load is successful.

snapshot_path: PathBuf

Path to the file that contains the microVM state to be loaded. Required: true

Trait Implementations

impl Clone for SnapshotLoadParams

fn clone(&self) -> SnapshotLoadParams

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SnapshotLoadParams

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SnapshotLoadParams

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for SnapshotLoadParams

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 Ord for SnapshotLoadParams

fn cmp(&self, other: &SnapshotLoadParams) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for SnapshotLoadParams

fn eq(&self, other: &SnapshotLoadParams) -> 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 PartialOrd for SnapshotLoadParams

fn partial_cmp(&self, other: &SnapshotLoadParams) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for SnapshotLoadParams

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
