Types

type CancelableTransport

type CancelableTransport interface {
	http.RoundTripper
	CancelRequest(req *http.Request)
}

CancelableTransport mimics http.Transport to provide an interface which can be substituted for testing (since the RoundTripper interface alone does not require the CancelRequest method)

type HTTPAction

type HTTPAction interface {
	HTTPRequest(url.URL) *http.Request
}

type HTTPClient

type HTTPClient interface {
	Do(context.Context, HTTPAction) (*http.Response, []byte, error)
}

type KeysAPI

type KeysAPI interface {
	Create(ctx context.Context, key, value string, ttl time.Duration) (*Response, error)
	Get(ctx context.Context, key string) (*Response, error)

	Watch(key string, idx uint64) Watcher
	RecursiveWatch(key string, idx uint64) Watcher
}

func NewDiscoveryKeysAPI

func NewDiscoveryKeysAPI(c HTTPClient) KeysAPI

func NewKeysAPI

func NewKeysAPI(c HTTPClient) KeysAPI

type MembersAPI

type MembersAPI interface {
	List(ctx context.Context) ([]httptypes.Member, error)
	Add(ctx context.Context, peerURL string) (*httptypes.Member, error)
	Remove(ctx context.Context, mID string) error
}

func NewMembersAPI

func NewMembersAPI(c HTTPClient) MembersAPI

type Node

	CreatedIndex  uint64 `json:"createdIndex"`
}

func (*Node) String

func (n *Node) String() string

type Nodes

type Nodes []*Node

type Response

type Response struct {
	Action   string `json:"action"`
	Node     *Node  `json:"node"`
	PrevNode *Node  `json:"prevNode"`
	Index    uint64
}

type SyncableHTTPClient

type SyncableHTTPClient interface {
	HTTPClient
	Sync(context.Context) error
	Endpoints() []string
}
