I declared an inline class

```auto
@JvmInline
value class Creator<T>(val type: KClass<T>);

```

And defined an interface

```auto
interface Itf {
    fun <T> creator(type: KClass<T>): Creator<T>;
}

```

I want to implment this interface by generating the bytecode directly by asm([https://asm.ow2.io/](https://asm.ow2.io/)).  
I found the function name in byte code is “creator-9k1ZQyY”

Here, the suffix “-9k1ZQyY” is added by kotlin compiler

This suffix is very important for bytecode generator.

My question:

If the interface and inline class are stable.  
Can kotlin compiler guarantee that suffix is stable too? Does that suffix have nothing to do with the version of kotlin-compiler?

This problem is resolved

kotlin-compiler guarantee it’s stable since 1.4.30,
