Enum OptionTargetType 

#[non_exhaustive]
pub enum OptionTargetType {
    TargetTypeUnknown,
    TargetTypeFile,
    TargetTypeExtensionRange,
    TargetTypeMessage,
    TargetTypeField,
    TargetTypeOneof,
    TargetTypeEnum,
    TargetTypeEnumEntry,
    TargetTypeService,
    TargetTypeMethod,
    UnknownValue(UnknownValue),
}

This indicates the types of entities that the field may apply to when used as an option. If it is unset, then the field may be freely used as an option on any kind of entity.

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.

TargetTypeUnknown

TargetTypeFile

TargetTypeExtensionRange

TargetTypeMessage

TargetTypeField

TargetTypeOneof

TargetTypeEnum

TargetTypeEnumEntry

TargetTypeService

TargetTypeMethod

UnknownValue(UnknownValue)

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

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

Implementations

impl OptionTargetType

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 OptionTargetType

fn clone(&self) -> OptionTargetType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OptionTargetType

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

Formats the value using the given formatter.

impl Default for OptionTargetType

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for OptionTargetType

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

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for OptionTargetType

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

Formats the value using the given formatter.

impl From<&str> for OptionTargetType

fn from(value: &str) -> Self

Converts to this type from the input type.

impl From<i32> for OptionTargetType

fn from(value: i32) -> Self

Converts to this type from the input type.

impl PartialEq for OptionTargetType

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

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

where S: Serializer,

Serialize this value into the given Serde serializer.
