<p>Hi,</p> <p>I&#39;m fairly new to Go, and I came across a function declaration that I don&#39;t understand. Is someone able to explain it to me?</p> <p>The <a href="" rel="nofollow">snippet</a> is:</p> <pre><code>func (s *statusSync) updateStatus(newIngressPoint []apiv1.LoadBalancerIngress) { ... } </code></pre> <p>I can see that it&#39;s a function called &#34;updateStatus&#34; with a parameter which is an array of apiv1.LoadBalancerIngress and that there doesn&#39;t appear to be a return type.</p> <p>What does the <code>(s *statusSync)</code> part mean? </p> <hr/>**评论:**<br/><br/>nevyn: <pre><p><a href="" rel="nofollow"></a></p></pre>chalk_nz: <pre><p>Perfect, thank you :)</p></pre>arrans: <pre><p>Keep in mind that methods aren&#39;t limited to structs as the above URL suggests. A broader introduction is available in the Go tour: <a href="" rel="nofollow"></a></p></pre>barryzzzzzz: <pre><p>(s *statusSync) called receiver. </p></pre>
