| using | flow::uint8_t = unsigned char | 
|  | Byte. Best way to represent a byte of binary data. This is 8 bits on all modern systems.

| using | flow::int8_t = signed char | 
|  | Signed byte. Prefer to use uint8_twhen representing binary data. This is 8 bits on all modern systems.

| using | flow::Fine_clock = boost::chrono::high_resolution_clock | 
|  | Clock used for delicate time measurements, such that the now()method gets the current time relative to some unknown but constant epoch (reference point).  More...

|  | 
| using | flow::Fine_time_pt = Fine_clock::time_point | 
|  | A high-res time point as returned by Fine_clock::now()and suitable for precise time math in general.
 | 
|  | 
| using | flow::Fine_duration = Fine_clock::duration | 
|  | A high-res time duration as computed from two Fine_time_pts.
 | 
|  | 
| using | flow::Error_code = boost::system::error_code | 
|  | Short-hand for a boost.system error code (which basically encapsulates an integer/ enumerror code and a pointer through which to obtain a statically stored message string); this is how Flow modules report errors to the user; and we humbly recommended all C++ code use the same techniques.
