Enum Preemptibility 

#[non_exhaustive]
pub enum Preemptibility {
    Unspecified,
    NonPreemptible,
    Preemptible,
    Spot,
    UnknownValue(UnknownValue),
}

Controls the use of preemptible instances within the group.

Working with unknown values

This enum is defined as #[non_exhaustive] because Google Cloud may add additional enum variants at any time. Adding new variants is not considered a breaking change. Applications should write their code in anticipation of:

• New values appearing in future releases of the client library, and
• New values received dynamically, without application changes.

Please consult the Working with enums section in the user guide for some guidelines.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Unspecified

Preemptibility is unspecified, the system will choose the appropriate setting for each instance group.

NonPreemptible

Instances are non-preemptible.

This option is allowed for all instance groups and is the only valid value for Master and Worker instance groups.

Preemptible

Instances are [preemptible] (https://cloud.google.com/compute/docs/instances/preemptible).

This option is allowed only for [secondary worker] (https://cloud.google.com/dataproc/docs/concepts/compute/secondary-vms) groups.

Spot

Instances are [Spot VMs] (https://cloud.google.com/compute/docs/instances/spot).

This option is allowed only for [secondary worker] (https://cloud.google.com/dataproc/docs/concepts/compute/secondary-vms) groups. Spot VMs are the latest version of [preemptible VMs] (https://cloud.google.com/compute/docs/instances/preemptible), and provide additional features.

UnknownValue(UnknownValue)

If set, the enum was initialized with an unknown value.

Applications can examine the value using Preemptibility::value or Preemptibility::name.

Implementations

impl Preemptibility

pub fn value(&self) -> Option<i32>

Gets the enum value.

Returns None if the enum contains an unknown value deserialized from the string representation of enums.

pub fn name(&self) -> Option<&str>

Gets the enum value as a string.

Returns None if the enum contains an unknown value deserialized from the integer representation of enums.

Trait Implementations

impl Clone for Preemptibility

fn clone(&self) -> Preemptibility

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Preemptibility

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

Formats the value using the given formatter.

impl Default for Preemptibility

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Preemptibility

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Preemptibility

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

Formats the value using the given formatter.

impl From<&str> for Preemptibility

fn from(value: &str) -> Self

Converts to this type from the input type.

impl From<i32> for Preemptibility

fn from(value: i32) -> Self

Converts to this type from the input type.

impl PartialEq for Preemptibility

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

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
