Struct Instance

pub struct Instance {
    pub name: String,
    pub config: String,
    pub display_name: String,
    pub node_count: i32,
    pub state: i32,
    pub labels: HashMap<String, String>,
    pub endpoint_uris: Vec<String>,
}

An isolated set of Cloud Spanner resources on which databases can be hosted.

Fields

name: String

Required. A unique identifier for the instance, which cannot be changed after the instance is created. Values are of the form projects/<project>/instances/[a-z][-a-z0-9]*[a-z0-9]. The final segment of the name must be between 2 and 64 characters in length.

config: String

Required. The name of the instance’s configuration. Values are of the form projects/<project>/instanceConfigs/<configuration>. See also [InstanceConfig][google.spanner.admin.instance.v1.InstanceConfig] and [ListInstanceConfigs][google.spanner.admin.instance.v1.InstanceAdmin.ListInstanceConfigs].

display_name: String

Required. The descriptive name for this instance as it appears in UIs. Must be unique per project and between 4 and 30 characters in length.

node_count: i32

Required. The number of nodes allocated to this instance. This may be zero in API responses for instances that are not yet in state READY.

See the documentation for more information about nodes.

state: i32

Output only. The current instance state. For [CreateInstance][google.spanner.admin.instance.v1.InstanceAdmin.CreateInstance], the state must be either omitted or set to CREATING. For [UpdateInstance][google.spanner.admin.instance.v1.InstanceAdmin.UpdateInstance], the state must be either omitted or set to READY.

labels: HashMap<String, String>

Cloud Labels are a flexible and lightweight mechanism for organizing cloud resources into groups that reflect a customer’s organizational needs and deployment strategies. Cloud Labels can be used to filter collections of resources. They can be used to control how resource metrics are aggregated. And they can be used as arguments to policy management rules (e.g. route, firewall, load balancing, etc.).

• Label keys must be between 1 and 63 characters long and must conform to the following regular expression: [a-z]([-a-z0-9]*[a-z0-9])?.
• Label values must be between 0 and 63 characters long and must conform to the regular expression ([a-z]([-a-z0-9]*[a-z0-9])?)?.
• No more than 64 labels can be associated with a given resource.

See https://goo.gl/xmQnxf for more information on and examples of labels.

If you plan to use labels in your own code, please note that additional characters may be allowed in the future. And so you are advised to use an internal label representation, such as JSON, which doesn’t rely upon specific characters being disallowed. For example, representing labels as the string: name + “” + value would prove problematic if we were to allow “” in a future release.

endpoint_uris: Vec<String>

Deprecated. This field is not populated.

Implementations

impl Instance

pub fn state(&self) -> State

Returns the enum value of state, or the default if the field is set to an invalid enum value.

pub fn set_state(&mut self, value: State)

Sets state to the provided enum value.

Trait Implementations

impl Clone for Instance

fn clone(&self) -> Instance

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Instance

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

Formats the value using the given formatter.

impl Default for Instance

fn default() -> Instance

Returns the “default value” for a type.

impl Message for Instance

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message to a buffer.

fn encode_length_delimited<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn decode<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for Instance

fn eq(&self, other: &Instance) -> 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.
