Enum TargetShape 

#[non_exhaustive]
pub enum TargetShape {
    Any,
    AnySingleZone,
    Balanced,
    UnknownValue(UnknownValue),
}

Available on crate features instances or region-instances only.

The enumerated type for the targetShape field.

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.

Any

GCE picks zones for creating VM instances to fulfill the requested number of VMs within present resource constraints and to maximize utilization of unused zonal reservations. Recommended for batch workloads that do not require high availability.

AnySingleZone

GCE always selects a single zone for all the VMs, optimizing for resource quotas, available reservations and general capacity. Recommended for batch workloads that cannot tollerate distribution over multiple zones. This the default shape in Bulk Insert and Capacity Advisor APIs.

Balanced

GCE prioritizes acquisition of resources, scheduling VMs in zones where resources are available while distributing VMs as evenly as possible across allowed zones to minimize the impact of zonal failure. Recommended for highly available serving workloads.

UnknownValue(UnknownValue)

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

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

Implementations

impl TargetShape

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 TargetShape

fn clone(&self) -> TargetShape

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TargetShape

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

Formats the value using the given formatter.

impl Default for TargetShape

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for TargetShape

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

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for TargetShape

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

Formats the value using the given formatter.

impl From<&str> for TargetShape

fn from(value: &str) -> Self

Converts to this type from the input type.

impl From<i32> for TargetShape

fn from(value: i32) -> Self

Converts to this type from the input type.

impl PartialEq for TargetShape

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

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

where S: Serializer,

Serialize this value into the given Serde serializer.
