newbie in go, i create a struct of interface so i can calls the underlying interface then transform in new method. when i called the struct method get errors: runtime: goroutine stack exceeds 1000000000-byte limit
inter.go
package inter
type Say interface {
Hello() string
}
greetings.go
package greetings
import (
"fmt"
"example.com/inter"
)
type Greetings struct {
Someone inter.Say
}
func (G Greetings) Hello() string {
return fmt.Sprintf("Hello, %v", G.Hello())
}
user.go
package user
type User struct {
Name string
Age int
}
func (U User) Hello() string {
return U.Name
}
main.go
package main
import (
"fmt"
"example.com/greetings"
"example.com/user"
)
func main() {
usr := user.User{
Name: "Lizzy",
Age: 25,
}
grt := greetings.Greetings{Someone: usr}
fmt.Println(grt.Hello())
}
type Greetings struct {
Someone inter.Say
}
func (G Greetings) Hello() string {
return fmt.Sprintf("Hello, %v", G.Hello())
}
Greetings.Hello mistakenly calls itself, where the intent appears to be to call the Hello implementation on the receiver's Someone field:
func (G Greetings) Hello() string {
return fmt.Sprintf("Hello, %v", G.Someone.Hello())
} // ^^^^^^^^^
