X::Parameter::WrongOrder Reference
Compilation error due to passing parameters in the wrong order
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 misplaced #
Returns the kind of misplaced parameter (for example "mandatory", "positional").
method parameter #
Returns the name of the (first) misplaced parameter
method after #
Returns a string describing other parameters after which the current parameter was illegally placed (for example "variadic", "positional" or "optional").
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.
