How to use function types in interfaces in Go-CodePudding

I have the following code

type SomeInterface interface {
    SomeFunc(int, string)
}

type IntStringFunc func(int, string)

func (f IntStringFunc) SomeFunc(i int, s string) {
    f(i, s)
}

What is the syntax for invoking the method SomeFunc on the function type IntStringFunc?

CodePudding user response：

The method calling syntax does not depend on the receiver type, it's always the same: value.methodName(params).

For example:

var f IntStringFunc = func(i int, s string) {
    fmt.Printf("f(%d, %s)\n", i, s)
}

f.SomeFunc(1, "one")

This will output (try it on the Go Playground):

f(1, one)

Since type of f is a function type, you can of course call it too like this:

f(1, "one")

Which of course will print the same.
