如何在go中释放内存？

I have a structure:

type xyz struct {
    x int
    y string
}

func f(){
    x := new(xyz) //allocating memory
}

But I cannot find any method to deallocate it in go.

• Is it not needed to deallocate it in golang?
• Is there any useful document for how memory allocation/deallocation happens in go?

Go is garbage collected language. You do not have to deallocate memory.

Articles on memory allocation and deallocation in Go.

1. Garbage collection
2. Heap and stack allocation
3. Discussion on allocation optimization
4. Variable allocation
