title: Erlang: reverse search in binaries
body: <p>Is there an analogue to <code>string:rstr()</code> for binaries?</p>
  
  <p>I am also puzzled by the fact that while the proposal <a href="http://erlang.org/eeps/eep-0009.html" rel="nofollow noreferrer">EEP-9</a> suggesting implementing this within <code>binary_string</code> module was adopted for R12B-2 the current <a href="http://erlang.org/doc/man/" rel="nofollow noreferrer">OTP docs</a> do not mention this module at all.</p>
