Types

type Event 

type Event struct {
	EventNID EventNID
	*gomatrixserverlib.Event

An Event is a gomatrixserverlib.Event with the numeric event ID attached. It is when performing bulk event lookup in the database.

type EventNID 

type EventNID int64

EventNID is a numeric ID for an event.

type EventNIDs added in v0.4.0 

type EventNIDs []EventNID

type EventStateKeyNID 

type EventStateKeyNID int64

EventStateKeyNID is a numeric ID for an event state_key.

type EventTypeNID 

type EventTypeNID int64

EventTypeNID is a numeric ID for an event type.

type MissingEventError 

type MissingEventError string

A MissingEventError is an error that happened because the roomserver was missing requested events from its database.

func (MissingEventError) Error 

func (e MissingEventError) Error() string

type MissingStateError added in v0.6.4 

type MissingStateError string

A MissingStateError is an error that happened because the roomserver was missing requested state snapshots from its databases.

func (MissingStateError) Error added in v0.6.4 

func (e MissingStateError) Error() string

type RejectedError added in v0.6.3 

type RejectedError string

A RejectedError is returned when an event is stored as rejected. The error contains the reason why.

func (RejectedError) Error added in v0.6.3 

func (e RejectedError) Error() string

type RoomInfo 

type RoomInfo struct {
	RoomNID     RoomNID
	RoomVersion gomatrixserverlib.RoomVersion
	// contains filtered or unexported fields
}

RoomInfo contains metadata about a room

func (*RoomInfo) CopyFrom added in v0.9.1 

func (r *RoomInfo) CopyFrom(r2 *RoomInfo)

func (*RoomInfo) IsStub 

func (r *RoomInfo) IsStub() bool

func (*RoomInfo) SetIsStub added in v0.9.0 

func (r *RoomInfo) SetIsStub(isStub bool)

func (*RoomInfo) SetStateSnapshotNID added in v0.9.0 

func (r *RoomInfo) SetStateSnapshotNID(nid StateSnapshotNID)

func (*RoomInfo) StateSnapshotNID 

func (r *RoomInfo) StateSnapshotNID() StateSnapshotNID

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
	gomatrixserverlib.EventReference
}

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.

type StateAtEventAndReferences added in v0.8.5 

type StateAtEventAndReferences []StateAtEventAndReference

func (StateAtEventAndReferences) EventIDs added in v0.8.6 

func (s StateAtEventAndReferences) EventIDs() string

func (StateAtEventAndReferences) Len added in v0.8.5 

func (s StateAtEventAndReferences) Len() int

func (StateAtEventAndReferences) Less added in v0.8.5 

func (s StateAtEventAndReferences) Less(a, b int) bool

func (StateAtEventAndReferences) Swap added in v0.8.5 

func (s StateAtEventAndReferences) Swap(a, b int)

type StateBlockNID 

type StateBlockNID int64

StateBlockNID is a numeric ID for a block of state data. These blocks of state data are combined to form the actual state.

type StateBlockNIDList 

type StateBlockNIDList struct {
	StateSnapshotNID StateSnapshotNID
	StateBlockNIDs   []StateBlockNID
}

StateBlockNIDList is used to return the result of bulk StateBlockNID lookups from the database.

type StateBlockNIDs added in v0.4.0 

type StateBlockNIDs []StateBlockNID

StateBlockNIDs is used to sort and dedupe state block NIDs.

func (StateBlockNIDs) Hash added in v0.4.0 

func (a StateBlockNIDs) Hash() []byte

func (StateBlockNIDs) Len added in v0.4.0 

func (a StateBlockNIDs) Len() int

type StateEntry 

type StateEntry struct {
	StateKeyTuple
	// The numeric ID for the event.
	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 added in v0.6.3 

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 []StateKeyTuple

func (StateKeyTupleSorter) Len added in v0.8.6 

func (s StateKeyTupleSorter) Len() int

func (s StateKeyTupleSorter) Swap(i, j int)

func (StateKeyTupleSorter) TypesAndStateKeysAsArrays added in v0.8.6 

func (s StateKeyTupleSorter) TypesAndStateKeysAsArrays() (eventTypeNIDs []int64, eventStateKeyNIDs []int64)

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.
