type RoomNID 

type RoomNID int64

RoomNID is a numeric ID for a room.

type StateAtEvent 

type StateAtEvent struct {
	// The state before the event.
	BeforeStateSnapshotNID StateSnapshotNID
	// True if this StateEntry is rejected. State resolution should then treat this
	// StateEntry as being a message event (not a state event).
	IsRejected bool
	// The state entry for the event itself, allows us to calculate the state after the event.
	StateEntry
}

StateAtEvent is the state before and after a matrix event.

func (StateAtEvent) IsStateEvent 

func (s StateAtEvent) IsStateEvent() bool

IsStateEvent returns whether the event the state is at is a state event.

type StateAtEventAndReference 

type StateAtEventAndReference struct {
	StateAtEvent
	EventID string
}

StateAtEventAndReference is StateAtEvent and gomatrixserverlib.EventReference glued together. It is used when looking up the latest events in a room in the database. The gomatrixserverlib.EventReference is used to check whether a new event references the event. The StateAtEvent is used to construct the current state of the room from the latest events.

	EventNID EventNID
}

A StateEntry is an entry in the room state of a matrix room.

func DeduplicateStateEntries 

func DeduplicateStateEntries(a []StateEntry) []StateEntry

Deduplicate takes a set of state entries and ensures that there are no duplicate (event type, state key) tuples. If there are then we dedupe them, making sure that the latest/highest NIDs are always chosen.

func (StateEntry) LessThan 

func (a StateEntry) LessThan(b StateEntry) bool

LessThan returns true if this state entry is less than the other state entry. The ordering is arbitrary and is used to implement binary search and to efficiently deduplicate entries.

type StateEntryList 

type StateEntryList struct {
	StateBlockNID StateBlockNID
	StateEntries  []StateEntry
}

StateEntryList is used to return the result of bulk state entry lookups from the database.

type StateKeyTuple 

type StateKeyTuple struct {
	// The numeric ID for the event type.
	EventTypeNID EventTypeNID
	// The numeric ID for the state key.
	EventStateKeyNID EventStateKeyNID
}

A StateKeyTuple is a pair of a numeric event type and a numeric state key. It is used to lookup state entries.

func (StateKeyTuple) IsCreate 

func (a StateKeyTuple) IsCreate() bool

func (StateKeyTuple) LessThan 

func (a StateKeyTuple) LessThan(b StateKeyTuple) bool

LessThan returns true if this state key is less than the other state key. The ordering is arbitrary and is used to implement binary search and to efficiently deduplicate entries.

type StateKeyTupleSorter 

type StateKeyTupleSorter []StateKeyTuple

func (StateKeyTupleSorter) Len 

func (s StateKeyTupleSorter) Len() int

func (StateKeyTupleSorter) Less

List the unique eventTypeNIDs and eventStateKeyNIDs. Assumes that the list is sorted.

type StateSnapshotNID 

type StateSnapshotNID int64

StateSnapshotNID is a numeric ID for the state at an event.

type UserRoomKeyPair 

type UserRoomKeyPair struct {
	RoomNID          RoomNID
