NewViewedStoredBottleCollection initializes viewed result type StoredBottleCollection from result type StoredBottleCollection using the given view.

Types

type Client

type Client struct {
	PickEndpoint goa.Endpoint
}

Client is the "sommelier" service client.

func NewClient

func NewClient(pick goa.Endpoint) *Client
