DslMarker

annotation class DslMarker(source)

When applied to annotation class X specifies that X defines a DSL language

The general rule:

  • an implicit receiver may belong to a DSL @X if marked with a corresponding DSL marker annotation

  • two implicit receivers of the same DSL are not accessible in the same scope

  • the closest one wins

  • other available receivers are resolved as usual, but if the resulting resolved call binds to such a receiver, it's a compilation error

Marking rules: an implicit receiver is considered marked with @Ann if

  • its type is marked, or

  • its type's classifier is marked

  • or any of its superclasses/superinterfaces
