func (*StreamingToken) WithUpdates 

func (t *StreamingToken) WithUpdates(other StreamingToken) StreamingToken

WithUpdates returns a copy of the StreamingToken with updates applied from another StreamingToken. If the latter StreamingToken contains a field that is not 0, it is considered an update, and its value will replace the corresponding value in the StreamingToken on which WithUpdates is called. If the other token has a log, they will replace any existing log on this token.

type SyncTokenType 

type SyncTokenType string

SyncTokenType represents the type of a sync token. It can be either "s" (representing a position in the whole stream of events) or "t" (representing a position in a room's topology/depth). 

const (
	// SyncTokenTypeStream represents a position in the server's whole
	// stream of events
	SyncTokenTypeStream SyncTokenType = "s"
	// SyncTokenTypeTopology represents a position in a room's topology.
	SyncTokenTypeTopology SyncTokenType = "t"
)
