X::Inheritance::Unsupported Reference
Compilation error due to inheriting from an ineligible type
What it is #
Routines #
Signatures are reproduced from the documentation, including their declared return types. A routine listed here is part of the type's published interface; whether Raku++ implements it is a separate question, answered by the examples below.
method child-typename #
The name of the type that tries to inherit.
method parent #
The type object that the child tried to inherit from.
Examples, run three ways #
Every example below comes from the official documentation, together with the output that documentation asserts. Each was then executed by Rakudo and by Raku++ when this page was built. Where the three agree, one result is shown; where they do not, all three are — because which of them is wrong is exactly the information worth having.
3 no-output
class X::Inheritance::Unsupported does X::Comp { }Not executed: the documentation states no expected output for this example.
enum E <Ex Ey>;
class B is E { };Not executed: the documentation states no expected output for this example.
E does not support inheritance, so B cannot inherit from it
