Overview

Package memcache is an auto-generated package for the Cloud Memorystore for Memcached API.

Google Cloud Memorystore for Memcached API is used for creating and managing Memcached instances in GCP.

Use of Context

The ctx passed to NewClient is used for authentication requests and for creating the underlying connection, but is not used for subsequent calls. Individual methods on the client use the ctx given to them.

To close the open connection, use the Close() method.

For information about setting deadlines, reusing contexts, and more please visit pkg.go.dev/cloud.google.com/go.

Functions

func DefaultAuthScopes 

func DefaultAuthScopes() []string

DefaultAuthScopes reports the default set of authentication scopes to use with this package.

Types

type ApplyParametersOperation 

type ApplyParametersOperation struct {
	// contains filtered or unexported fields
}

ApplyParametersOperation manages a long-running operation from ApplyParameters.

func (*ApplyParametersOperation) Done 

func (op *ApplyParametersOperation) Done() bool

Done reports whether the long-running operation has completed.

func (*ApplyParametersOperation) Metadata 

func (op *ApplyParametersOperation) Metadata() (*memcachepb.OperationMetadata, error)

Metadata returns metadata associated with the long-running operation. Metadata itself does not contact the server, but Poll does. To get the latest metadata, call this method after a successful call to Poll. If the metadata is not available, the returned metadata and error are both nil.

func (*ApplyParametersOperation) Name 

func (op *ApplyParametersOperation) Name() string

Name returns the name of the long-running operation. The name is assigned by the server and is unique within the service from which the operation is created.

func (*ApplyParametersOperation) Poll 

func (op *ApplyParametersOperation) Poll(ctx context.Context, opts ...gax.CallOption) (*memcachepb.Instance, error)

Poll fetches the latest state of the long-running operation.

Poll also fetches the latest metadata, which can be retrieved by Metadata.

If Poll fails, the error is returned and op is unmodified. If Poll succeeds and the operation has completed with failure, the error is returned and op.Done will return true. If Poll succeeds and the operation has completed successfully, op.Done will return true, and the response of the operation is returned. If Poll succeeds and the operation has not completed, the returned response and error are both nil.

func (*ApplyParametersOperation) Wait 

func (op *ApplyParametersOperation) Wait(ctx context.Context, opts ...gax.CallOption) (*memcachepb.Instance, error)

Wait blocks until the long-running operation is completed, returning the response and any errors encountered.

See documentation of Poll for error-handling information.

type CloudMemcacheClient 

type CloudMemcacheClient struct {

	// LROClient is used internally to handle longrunning operations.
	// It is exposed so that its CallOptions can be modified if required.
	// Users should not Close this client.

	// The call options for this service.
	CallOptions *CloudMemcacheCallOptions
	// contains filtered or unexported fields
}

CloudMemcacheClient is a client for interacting with Cloud Memorystore for Memcached API.

Methods, except Close, may be called concurrently. However, fields must not be modified concurrently with method calls.

func NewCloudMemcacheClient 

func NewCloudMemcacheClient(ctx context.Context, opts ...option.ClientOption) (*CloudMemcacheClient, error)

NewCloudMemcacheClient creates a new cloud memcache client.

Configures and manages Cloud Memorystore for Memcached instances.

The memcache.googleapis.com service implements the Google Cloud Memorystore for Memcached API and defines the following resource model for managing Memorystore Memcached (also called Memcached below) instances: 

The service works with a collection of cloud projects, named: /projects/*

Each project has a collection of available locations, named: /locations/*

Each location has a collection of Memcached instances, named:
/instances/*

As such, Memcached instances are resources of the form:
/projects/{project_id}/locations/{location_id}/instances/{instance_id}

Note that location_id must be a GCP region; for example: 

projects/my-memcached-project/locations/us-central1/instances/my-memcached
