Overview
We can have an unexported struct with exported fields. For example, consider the following declaration:
package foo
type s struct {
I int
}
func F() s {
return s{}
}This struct can be accessed in another package as follows:
package main
func main() {
a:=foo.F()
a.I=1
_=foo.F().I
}This technique is commonly used, when declaring structs in handlers for encoding/decoding to/from JSON
