Upon success, the delegate should return the byte-based index of
the consumed pattern (tail end of it).
Failure to match a pattern should be indicated by returning an Eof
Each pattern is expected to be stripped of the delimiter.
An end-of-file condition causes trailing content to be
placed into the token. Requests made beyond Eof result
in empty matches (length is zero).
Additional iterator and/or reader instances
will operate in lockstep when bound to a common buffer.
Iterator support.
