Type::DeclaredAt - A class to represent where a type or coercion was declared
version 0.05
my $declared = Type::DeclaredAt->new_from_caller(1); print $declared->description();
This class provides a thin wrapper around some of the return values from Perl's caller() built-in. It's used internally to identify where types and coercions are being declared, which is useful when generating error messages.
caller()
This class provides the following methods.
Given a call stack depth, this method returns a new Type::DeclaredAt object.
Type::DeclaredAt
Returns the call stack information recorded when the object was created. These values are always populated.
Returns the subroutine from the call stack. This may be an udnef
udnef
Returns true if there is a subroutine name associated with this object.
Puts all the information together into a single string like "declared in package Foo::Bar (.../Foo/Bar.pm) at line 42 in sub named blah".
