- !ruby/struct:SM::Flow::P 
  body: Decodes <em>str</em> (which may contain binary data) according to the format string, returning an array of each value extracted. The format string consists of a sequence of single-character directives, summarized in the table at the end of this entry. Each directive may be followed by a number, indicating the number of times to repeat with this directive. An asterisk (``<tt>*</tt>'') will use up all remaining elements. The directives <tt>sSiIlL</tt> may each be followed by an underscore (``<tt>_</tt>'') to use the underlying platform's native size for the specified type; otherwise, it uses a platform-independent consistent size. Spaces are ignored in the format string. See also <tt>Array#pack</tt>.
