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 source #
method source()Returns the value that failed to coerce.
method target #
method target()Returns the type to which the coercion was attempted.
method reason #
method reason(--> Str:D)Returns Str:D.
Returns the reason that the conversion failed.
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.

class X::Numeric::CannotConvert is Exception { }Not executed: the documentation states no expected output for this example.
say Inf.Int;
CATCH { default { put .^name, ': ', .Str } };
# OUTPUT: «X::Numeric::CannotConvert: Cannot convert Inf to Int»X::Numeric::CannotConvert: Cannot convert Inf to Int
Documentation, Rakudo and Raku++ all agree.
