Go中的new（Struct）和＆Struct {}之间有什么区别？

Question

They seem to be the same:

package main

import "fmt"

type S struct {
    i int
}

func main() {
  var s1 *S = new(S)
  fmt.Println(s1)

  var s2 *S = &S{}
  fmt.Println(s2)  // Prints the same thing.
}

Update:

Hm. I just realized that there's no obvious way to initialize S.i using new. Is there a way to do that? new(S{i:1}) does not seem to work :/

Answer 1

From the documentation:

As a limiting case, if a composite literal contains no fields at all, it creates a zero value for the type. The expressions new(File) and &File{} are equivalent.
