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) (r GetResult)

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

func (GetResult) Extract

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

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

type ListOpts

type ListOpts struct {
	// admin-only option. Set it to true to see all tenant volumes.
	AllTenants bool `q:"all_tenants"`
	// List only volumes that contain Metadata.
	Metadata map[string]string `q:"metadata"`
	// List only volumes that have Name as the display name.
	Name string `q:"display_name"`
	// List only volumes that have a status of Status.
	Status string `q:"status"`
}

ListOpts holds options for listing Volumes. It is passed to the volumes.List function.

func (ListOpts) ToVolumeListQuery

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

ToVolumeListQuery formats a ListOpts into a query string.
