Golang 匿名函数使用
2022-07-03 16:07:00 【CmderQ】
一 序言
最近在研究NSQ中间件,在研究这个中间件的过程中,发现了一些自己在平时开发工作中未使用到的Golang特性;决定记录下在这个过程中学习到的一些知识;本篇文章要写的,是关于Golang匿名函数的使用
二 匿名函数
匿名函数没有函数名只有函数体,他可以作为一种类型被赋值给函数类型的变量,匿名函数也往往以变量方式传递。
Go语言支持随时在代码里定义匿名函数。 匿名函数,由一个不带函数名的函数声明和函数体组成。简而言之,就是匿名函数可以将作为普通变量使用:能在函数中传递或者是赋值给变量。
三 使用Demo
在NSQ中,使用匿名函数的代码如下:
exitCh := make(chan error)
var once sync.Once
exitFunc := func边栏推荐
