How to print enum's value

[LukyGuyLucky]

Always the most recent build---

enum Status{
	Idle,
	Running,
	Finishing,
	Error(int)
}

test "enum_codegen_auto_call"{
	let s=Status::Idle;
	"s={s}";
	printf("%d\n",s);//ok
}

error

@LukyGuyLucky Need to do these two steps:

• Step-1: Impl the operator "{}" for Status.
• Step-2: declare the Status explicitly and call the Status constructor.

the test

lang>zc run print-enum.zc
   Compiling print-enum.zc
     Running print-enum.exe
s=Idle
0

zenc\lang>

the source

import "std/core.zc"
import "std/string.zc"

enum Status{
	Idle,
	Running,
	Finishing,
	Error(int)
}

impl Status {
    
    // Step-1: Impl the operator "{}"    
    fn to_string(self) -> char* {
        match *self {
            Status::Idle => return "Idle",
            Status::Running => return "Running",
            Status::Finishing => return "Finishing",
            Status::Error(i) => return "Error({i})",
        }
    }
}

test "enum_codegen_auto_call"{
    // Step-2: declare the `Status` explicitly and call the `Status` constructor.
	let s: Status = Status::Idle();
    "s={s}";
	printf("%d\n", s);//ok
}

Thank.I have thought that by default zenc println will print primitive types and enums,not expecting a manul reflection between enum value and String.My fault.
