❓ What’s the difference between @Stable and @StableMarker ? 🤔🧵

[Csaba Kozák]

@StableMarker is a meta-annotation, which is added to annotations which indicate a stability of a type. Apps should not use it directly i think. 🙂

[yousefa2]

@StableMarker is applied to other annotations to indicate that any type annotated with this other annotations is stable.

@Stable annotation is in itself annotated with @StableMarker

Stability means:

• Calls to equal has the same result of any two instances with the same content
• Composition is aware when public properties change
• All public properties of the annotated type is stable
