Enum State 

#[non_exhaustive]
pub enum State {
    NotKnown,
    Ready,
    Creating,
    Resizing,
    Disabled,
    UnknownValue(UnknownValue),
}

Possible states of a cluster.

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.

NotKnown

The state of the cluster could not be determined.

Ready

The cluster has been successfully created and is ready to serve requests.

Creating

The cluster is currently being created, and may be destroyed if the creation process encounters an error. A cluster may not be able to serve requests while being created.

Resizing

The cluster is currently being resized, and may revert to its previous node count if the process encounters an error. A cluster is still capable of serving requests while being resized, but may exhibit performance as if its number of allocated nodes is between the starting and requested states.

Disabled

The cluster has no backing nodes. The data (tables) still exist, but no operations can be performed on the cluster.

UnknownValue(UnknownValue)

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

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

Implementations

impl State

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 State

fn clone(&self) -> State

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for State

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

Formats the value using the given formatter.

impl Default for State

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for State

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

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for State

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

Formats the value using the given formatter.

impl From<&str> for State

fn from(value: &str) -> Self

Converts to this type from the input type.

impl From<i32> for State

fn from(value: i32) -> Self

Converts to this type from the input type.

impl PartialEq for State

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

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

where S: Serializer,

Serialize this value into the given Serde serializer.
