-// A wrapper around a memory buffer that allows circular read and write with a
-// selectable wrapping position. Buffer layout (after wrap; H is header):
-// -----------------------------------------------------------
-// | H | Beginning           | End           | Middle        |
-// -----------------------------------------------------------
-//  ^---- Non-wrapping -----^ ^--------- Wrapping ----------^
-// The non-wrapping part is never overwritten. The wrapping part will be
-// circular. The very first part is the header (see the BufferData struct
-// below). It consists of the following information:
-// - Length written to the buffer (not including header).
-// - Wrapping position.
-// - End position of buffer. (If the last byte is at x, this will be x + 1.)
-// Users of wrappers around the same underlying buffer must ensure that writing
-// is finished before reading is started.
