ClientInfo represents the client information

type Indexer

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

Indexer provides a index for a ordered list that supports queries in O(1). All methods are not concurrency-safe.

func NewIndexer

func NewIndexer() *Indexer

NewIndexer is the constructor of Indexer.

func (*Indexer) GetByID

func (i *Indexer) GetByID(id string) *list.Element

GetByID returns the value for the given id. Return nil if not found. Notice: Any access to the return *list.Element also require the mutex, because the Set method can modify the Value for *list.Element when updating the Value for the same id. If the caller needs the Value in *list.Element, it must get the Value before the next Set is called.

func (*Indexer) Iterate

func (i *Indexer) Iterate(fn func(elem *list.Element), offset, n uint)

Iterate iterates at most n elements in the list begin from offset. Notice: Any access to the *list.Element in fn also require the mutex, because the Set method can modify the Value for *list.Element when updating the Value for the same id. If the caller needs the Value in *list.Element, it must get the Value before the next Set is called.

func (*Indexer) Len

func (i *Indexer) Len() int

Len returns the length of list.

func (*Indexer) Remove

func (i *Indexer) Remove(id string) *list.Element

Remove removes and returns the value for the given id. Return nil if not found.

func (*Indexer) Set

func (i *Indexer) Set(id string, value interface{})

Set sets the value for the id.

type SessionInfo

type SessionInfo struct {
	ClientID              string     `json:"client_id"`
	Status                string     `json:"status"`
	CleanSession          bool       `json:"clean_session"`
	Subscriptions         uint64     `json:"subscriptions"`
	MaxInflight           uint16     `json:"max_inflight"`
	InflightLen           uint64     `json:"inflight_len"`
	MaxMsgQueue           int        `json:"max_msg_queue"`
	MsgQueueLen           uint64     `json:"msg_queue_len"`
	AwaitRelLen           uint64     `json:"await_rel_len"`
	Qos0MsgDroppedTotal   uint64     `json:"qos0_msg_dropped_total"`
	Qos1MsgDroppedTotal   uint64     `json:"qos1_msg_dropped_total"`
	Qos2MsgDroppedTotal   uint64     `json:"qos2_msg_dropped_total"`
	Qos0MsgDeliveredTotal uint64     `json:"qos0_msg_delivered_total"`
	Qos1MsgDeliveredTotal uint64     `json:"qos1_msg_delivered_total"`
	Qos2MsgDeliveredTotal uint64     `json:"qos2_msg_delivered_total"`
	ConnectedAt           *time.Time `json:"connected_at"`
	DisconnectedAt        *time.Time `json:"disconnected_at"`
}

SessionInfo represents the session information

	Name              string `json:"name"`
	Qos               uint32 `json:"qos"`
	NoLocal           bool   `json:"no_local"`
