Implementations

impl VZDiskImageSynchronizationMode

pub const Full: Self

The data is synchronized to the permanent storage holding the disk image. No synchronized data is lost on panic or loss of power.

pub const Fsync: Self

Synchronize the data to the drive.

This mode synchronizes the data with the drive, but does not ensure the data is moved from the disk’s internal cache to permanent storage.

This is a best-effort mode with the same guarantees as the fsync() system call.

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 that case, the disk image cannot safely be reused on failure.

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

Trait Implementations

impl Clone for VZDiskImageSynchronizationMode

fn clone(&self) -> VZDiskImageSynchronizationMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VZDiskImageSynchronizationMode

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

Formats the value using the given formatter.

impl Encode for VZDiskImageSynchronizationMode

const ENCODING: Encoding = NSInteger::ENCODING

The Objective-C type-encoding for this type.

impl Hash for VZDiskImageSynchronizationMode

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 VZDiskImageSynchronizationMode

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

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

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