## NAME
    [Specio::DeclaredAt](https://www.chedong.com/phpMan.php/perldoc/Specio%3A%3ADeclaredAt/markdown) - A class to represent where a type or coercion was declared

## VERSION
    version 0.47

## SYNOPSIS
        my $declared = [Specio::DeclaredAt](https://www.chedong.com/phpMan.php/perldoc/Specio%3A%3ADeclaredAt/markdown)->[new_from_caller(1)](https://www.chedong.com/phpMan.php/man/newfromcaller/1/markdown);

        print $declared->description;

## 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.

## API
    This class provides the following methods.

  [Specio::DeclaredAt](https://www.chedong.com/phpMan.php/perldoc/Specio%3A%3ADeclaredAt/markdown)->new_from_caller($depth)
    Given a call stack depth, this method returns a new "[Specio::DeclaredAt](https://www.chedong.com/phpMan.php/perldoc/Specio%3A%3ADeclaredAt/markdown)" object.

  $declared_at->package, $declared_at->filename, $declared_at->line
    Returns the call stack information recorded when the object was created. These values are always
    populated.

  $declared_at->subroutine
    Returns the subroutine from the call stack. This may be an "udnef"

  $declared_at->has_subroutine
    Returns true if there is a subroutine name associated with this object.

  $declared_at->description
    Puts all the information together into a single string like "declared in package [Foo::Bar](https://www.chedong.com/phpMan.php/perldoc/Foo%3A%3ABar/markdown)
    (.../Foo/Bar.pm) at line 42 in sub named blah".
