might be nice to split this into its own header

Will consider, though having a header with just a single typedef/using feels a
little silly....

+using ChannelId = uint64_t;
 
 }  // namespace system
 
 namespace embedder {
 
 class PlatformSupport;
 class ProcessDelegate;
 
 // This is a type that's opaque to users of the embedder API (which only

@@ skipping 19 matching lines @@
 // after |ShutdownIPCSupport()|.
 extern ProcessType g_process_type;
 
 }  // namespace internal
 
 }  // namepace embedder
 
 }  // namespace mojo
 
 #endif  // MOJO_EDK_EMBEDDER_EMBEDDER_INTERNAL_H_
