-// SyncNetworkEvents represent a single client <-> server sync protocol event

-// to send a sync protocol request (such as GetUpdates or Commit) to the server,
-// and when the server responds. Note that the requests and responses themselves
-// are modelled by {GetUpdates, Commit}x{Request,Response} objects.

-// These objects are intended to be used for displaying information on
-// about:sync.  They should be considered to be immutable and opaque.  No
-// program behavior should depend on their contents.
-//
-// Each type of request can maintain its own set of additional metadata and have
-// its own custom serialization routines.  For example, the "configure"
-// GetUpdates request will include information about its "origin" in its debug
-// info.
