func functionname(parametername type) returntype {//function body} 函数声明以关键字 func 开头,后面是函数名字,接着是在 ( 和 ) 之间指定的参数列表,然后是函数的返回类型。指定参数的语法为参数名称后面跟着参数类型。可以指定任意数量的参数,形式为:(parameter1 type, parameter2 type)。最后是由 { 和 } ...
funcfunctionName(parameter_list)(return_value_list){…}// parameter_list 是参数列表// return_value_list 是返回值列表 下边有详细的讲解 函数的特性 无需声明原型。 (1) 支持不定长变参。 支持多返回值。 支持命名返回参数。 支持匿名函数和闭包。 不支持 嵌套 (nested)、重载 (overload) 和 默认参数 ...
before the type name of the last parameter you can indicate that it takes zero or more of those parameters. // The function is invoked like any other function except we can pass as many arguments as we want. func adder(args ...int) int { total := 0 for _, v := range args { ...
[]里面的这一串T int|float64|string,叫类型参数列表(type parameter list),表示的是我们定义了几个泛型的参数。我们例子当中只有1个,下面的例子中,我们会创建多个。 最后面的[]T这个我们就很熟悉了,就是申请一个切片类型,比如常见的:[]int, []string 等等,只不过我们这里的类型是T,也就是参数列表里面定义的...

- Do not store Contexts inside a struct type; instead, pass a Context explicitly to each function that needs it. The Context should be the first parameter, typically named ctx;不要把Context存在一个结构体当中,显式地传入函数。Context变量需要作为第一个参数使用,一般命名为ctx; ...
