Overview

It is also possible to have an inline function with defer.

Example

Let’s see an example of that.

package main
import "fmt"
func main() {
defer func() { fmt.Println("In inline defer") }()
fmt.Println("Executed")
}

Output

Executed
In inline defer

In the above code we have defer with a inline function

defer func() { fmt.Println("In inline defer") }()

This is allowed in go. Also note that it is mandatory to add “()” after the function otherwise compiler will raise error

expression in defer must be function call

As seen from the output, that the inline function is called after everything in the main is executed and before main returns. That is why

Executed in main

is printed before

In inline Defer
