What's the right way to clear a bytes.Buffer in golang? : <p>I'm trying to clear a <code>bytes.Buffer</code>, but there's no such function in the document</p>

<p>Maybe I should just renew the buffer? What's the right way to do it?</p>

<pre><code>buffer   = bytes.NewBufferString("")
buffer.Grow (30000)
</code></pre>
