英文:
create generic function which can accept any function with its related args for later execution
问题
是否可以创建一个通用函数，该函数可以接受任何其他函数及其相关参数，并在以后用于执行传递的函数。我有一个需求，计划首先收集所有这些调用，并维护这些"作业"的一些元数据，然后通过Go协程稍后执行它们。
// 一种作业函数
func someCoolJob(arg1 type1, arg2 type2) type3 {
// 进行处理
return "type3的值"
}
现在是否可以创建一个通用函数，可以接受任何签名的函数。以前我在Python中做过类似的实现，Go中是否有类似的方法？
func processor(someFunc, relatedArgs){
// 在这里保存一些执行信息/跟踪状态
// 稍后可以在我的代码中执行以下操作
go someFunc(relatedArgs)
}
在Go中是否有更好的组织方式？其他实现方式？
英文:
Is it possible to create a generic function which can accept any other function with its related arguments which can be used later to execute the passed function. I have a requirement where I am planning to first collect all these calls and maintain some metadata of these "jobs" and then execute them later via go routines.
// some kind of job function
func someCoolJob(arg1 type1, arg2 type2) type3 {
// do processing
return "value of type3"
}
Now is it possible to create a generic function which can take any function with any signature. Previously I have done similar implementation in python, is there some way in go ?
func processor(someFunc, relatedArgs){
// I will save some execution info/ tracking state for someFunc here
// later I can do something like below in my code
go someFunc(relatedArgs)
}
Is there some better way to organise this in go ? Some other way of implementation ?

通过使用闭包将参数传递。
将processor更改为接受没有参数的函数。
func processor(fn func()){
go fn()
}
使用闭包传递函数和参数：
processor(func() { someCoolJob(arg1, arg2) })
英文:
Pass the arguments through using a closure.
Change processor to take a function with with no arguments.
func processor(fn func()){
go fn()
}
Pass the function and arguments using a closure:
processor(func() { someCoolJob(arg1, arg2) })
