Implementations

impl VZDiskSynchronizationMode

pub const Full: Self

Perform all synchronization operations as requested by the guest OS.

With VZDiskSynchronizationModeFull, “flush” and “barrier” commands from the guest result in their counterpart synchronization commands being sent to the disk implementation.

pub const None: Self

Do not synchronize the data with the permanent storage. This option does not guarantee data integrity if any error condition occurs such as disk full on the host, panic, power loss, etc.

This mode is useful when a virtual machine is only run once to perform a task to completion or failure. In case of failure, the state of blocks on disk and their order is undefined.

Using this mode may result in improved performance since no synchronization with the underlying storage is necessary.

Trait Implementations

impl Clone for VZDiskSynchronizationMode

fn clone(&self) -> VZDiskSynchronizationMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VZDiskSynchronizationMode

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

Formats the value using the given formatter.

impl Encode for VZDiskSynchronizationMode

const ENCODING: Encoding = NSInteger::ENCODING

The Objective-C type-encoding for this type.

impl Hash for VZDiskSynchronizationMode

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 VZDiskSynchronizationMode

fn cmp(&self, other: &VZDiskSynchronizationMode) -> 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 VZDiskSynchronizationMode

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

fn partial_cmp(&self, other: &VZDiskSynchronizationMode) -> 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.
