Enum Usage 

#[non_exhaustive]
pub enum Usage {
    Unspecified,
    ForVpc,
    ExternalToVpc,
    ForMigration,
    UnknownValue(UnknownValue),
}

Possible usage of an internal range.

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

Unspecified usage is allowed in calls which identify the resource by other fields and do not need Usage set to complete. These are, i.e.: GetInternalRange and DeleteInternalRange. Usage needs to be specified explicitly in CreateInternalRange or UpdateInternalRange calls.

ForVpc

A VPC resource can use the reserved CIDR block by associating it with the internal range resource if usage is set to FOR_VPC.

ExternalToVpc

Ranges created with EXTERNAL_TO_VPC cannot be associated with VPC resources and are meant to block out address ranges for various use cases, like for example, usage on-prem, with dynamic route announcements via interconnect.

ForMigration

Ranges created FOR_MIGRATION can be used to lock a CIDR range between a source and target subnet. If usage is set to FOR_MIGRATION, the peering value has to be set to FOR_SELF or default to FOR_SELF when unset.

UnknownValue(UnknownValue)

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

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

Implementations

impl Usage

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 Usage

fn clone(&self) -> Usage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Usage

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

Formats the value using the given formatter.

impl Default for Usage

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Usage

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

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Usage

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

Formats the value using the given formatter.

impl From<&str> for Usage

fn from(value: &str) -> Self

Converts to this type from the input type.

impl From<i32> for Usage

fn from(value: i32) -> Self

Converts to this type from the input type.

impl PartialEq for Usage

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

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

where S: Serializer,

Serialize this value into the given Serde serializer.
