<p>Using <code>Reader</code> to parse input helps to ensure that no byte of the input
will be accidentally processed more than once. Using <code>Reader</code> in
conjunction with <code>read_all</code> and <code>read_all_optional</code> helps ensure that no
byte of the input is accidentally left unprocessed. The methods of <code>Reader</code>
never panic, so <code>Reader</code> also assists the writing of panic-free code.</p>
<p>* <code>Reader</code> is not strictly forward-only because of the method
<code>get_input_between_marks</code>, which is provided mainly to support calculating
digests over parsed data.</p>
