NAME

       Type::Tiny::Duck - type constraints based on the "can" method

STATUS

       This module is covered by the Type-Tiny stability policy.

DESCRIPTION

       Type constraints of the general form "{ $_->can("method") }".

       This package inherits from Type::Tiny; see that for most documentation.  Major differences
       are listed below:

   Attributes
       "methods"
           An arrayref of method names.

       "constraint"
           Unlike Type::Tiny, you cannot pass a constraint coderef to the constructor.  Instead
           rely on the default.

       "inlined"
           Unlike Type::Tiny, you cannot pass an inlining coderef to the constructor.  Instead
           rely on the default.

       "parent"
           Parent is always Types::Standard::Object, and cannot be passed to the constructor.

   Methods
       "stringifies_to($constraint)"
           See Type::Tiny::ConstrainedObject.

       "numifies_to($constraint)"
           See Type::Tiny::ConstrainedObject.

       "with_attribute_values($attr1 => $constraint1, ...)"
           See Type::Tiny::ConstrainedObject.

   Exports
       Type::Tiny::Duck can be used as an exporter.

         use Type::Tiny::Duck HttpClient => [ 'get', 'post' ];

       This will export the following functions into your namespace:

       "HttpClient"
       "is_HttpClient( $value )"
       "assert_HttpClient( $value )"
       "to_HttpClient( $value )"

       Multiple types can be exported at once:

         use Type::Tiny::Duck (
           HttpClient   => [ 'get', 'post' ],
           FtpClient    => [ 'upload', 'download' ],
         );
