Types

type CreateOpts

type CreateOpts struct {
	// OPTIONAL
	Description string
	// OPTIONAL
	Force bool
	// OPTIONAL
	Metadata map[string]interface{}
	// OPTIONAL
	Name string
	// REQUIRED
	VolumeID string
}

CreateOpts contains options for creating a Snapshot. This object is passed to the snapshots.Create function. For more information about these parameters, see the Snapshot object.

func (CreateOpts) ToSnapshotCreateMap

func (opts CreateOpts) ToSnapshotCreateMap() (map[string]interface{}, error)

ToSnapshotCreateMap assembles a request body based on the contents of a CreateOpts.

type CreateOptsBuilder

type CreateOptsBuilder interface {
	ToSnapshotCreateMap() (map[string]interface{}, error)
}

CreateOptsBuilder allows extensions to add additional parameters to the Create request.

type CreateResult

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

CreateResult contains the response body and error from a Create request.

func Create

func Create(client *gophercloud.ServiceClient, opts CreateOptsBuilder) CreateResult

Create will create a new Snapshot based on the values in CreateOpts. To extract the Snapshot object from the response, call the Extract method on the CreateResult.

func (CreateResult) Extract

func (r CreateResult) Extract() (*Snapshot, error)

Extract will get the Snapshot object out of the commonResult object.

type DeleteResult

type DeleteResult struct {
	gophercloud.ErrResult
}

DeleteResult contains the response body and error from a Delete request.

func Delete

func Delete(client *gophercloud.ServiceClient, id string) DeleteResult

Delete will delete the existing Snapshot with the provided ID.

type GetResult

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

GetResult contains the response body and error from a Get request.

func Get

func Get(client *gophercloud.ServiceClient, id string) GetResult

Get retrieves the Snapshot with the provided ID. To extract the Snapshot object from the response, call the Extract method on the GetResult.

func (GetResult) Extract

func (r GetResult) Extract() (*Snapshot, error)

Extract will get the Snapshot object out of the commonResult object.

type ListOpts

type ListOpts struct {
	Name     string `q:"display_name"`
	Status   string `q:"status"`
	VolumeID string `q:"volume_id"`
}

ListOpts hold options for listing Snapshots. It is passed to the snapshots.List function.

func (ListOpts) ToSnapshotListQuery

func (opts ListOpts) ToSnapshotListQuery() (string, error)

ToSnapshotListQuery formats a ListOpts into a query string.

type ListOptsBuilder

type ListOptsBuilder interface {
	ToSnapshotListQuery() (string, error)
}

ListOptsBuilder allows extensions to add additional parameters to the List request.

type ListResult

type ListResult struct {
	pagination.SinglePageBase
}

ListResult is a pagination.Pager that is returned from a call to the List function.

func (ListResult) IsEmpty

func (r ListResult) IsEmpty() (bool, error)

IsEmpty returns true if a ListResult contains no Snapshots.

type Snapshot

type Snapshot struct {
	// Currect status of the Snapshot.
	Status string `mapstructure:"status"`

	// Display name.
	Name string `mapstructure:"display_name"`

	// Instances onto which the Snapshot is attached.
	Attachments []string `mapstructure:"attachments"`

	// Logical group.
	AvailabilityZone string `mapstructure:"availability_zone"`

	// Is the Snapshot bootable?
	Bootable string `mapstructure:"bootable"`

	// Date created.
	CreatedAt string `mapstructure:"created_at"`

	// Display description.
	Description string `mapstructure:"display_discription"`

	// See VolumeType object for more information.
	VolumeType string `mapstructure:"volume_type"`

	// ID of the Snapshot from which this Snapshot was created.
	SnapshotID string `mapstructure:"snapshot_id"`

	// ID of the Volume from which this Snapshot was created.
	VolumeID string `mapstructure:"volume_id"`

	// User-defined key-value pairs.
	Metadata map[string]string `mapstructure:"metadata"`

	// Unique identifier.
	ID string `mapstructure:"id"`

	// Size of the Snapshot, in GB.
	Size int `mapstructure:"size"`
}

Snapshot contains all the information associated with an OpenStack Snapshot.

func ExtractSnapshots

func ExtractSnapshots(page pagination.Page) ([]Snapshot, error)

ExtractSnapshots extracts and returns Snapshots. It is used while iterating over a snapshots.List call.

type UpdateMetadataOpts

type UpdateMetadataOpts struct {
	Metadata map[string]interface{}
