X::NoDispatcher Reference

Error due to calling a dispatch command in an ineligible scope

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 redispatcher #

method redispatcher(--> Str:D)

Returns Str:D.

Returns the name of the redispatcher function that did not succeed.

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.
