NAME

       Moose::Meta::TypeConstraint::DuckType - Type constraint for duck typing

VERSION

       version 2.2009

DESCRIPTION

       This class represents type constraints based on an enumerated list of required methods.

INHERITANCE

       "Moose::Meta::TypeConstraint::DuckType" is a subclass of Moose::Meta::TypeConstraint.

METHODS

   Moose::Meta::TypeConstraint::DuckType->new(%options)
       This creates a new duck type constraint based on the given %options.

       It takes the same options as its parent, with several exceptions. First, it requires an
       additional option, "methods". This should be an array reference containing a list of
       required method names. Second, it automatically sets the parent to the "Object" type.

       Finally, it ignores any provided "constraint" option. The constraint is generated
       automatically based on the provided "methods".

   $constraint->methods
       Returns the array reference of required methods provided to the constructor.

   $constraint->create_child_type
       This returns a new Moose::Meta::TypeConstraint object with the type as its parent.

       Note that it does not return a "Moose::Meta::TypeConstraint::DuckType" object!
