NAME

       HTML::FormFu::Constraint::File - File Upload Constraint

DESCRIPTION

       Ensure the submitted value is a file upload.

       This Constraint is not needed if you use any of the "File::*" Constraints, as they all
       make the same check as this Constraint does.

LIMITATIONS

       This can only verify that your CGI backend (CGI, Catalyst, CGI::Simple) thinks it was a
       file upload. If the user submits a filename which doesn't exist on their system, you will
       probably get a valid HTML::FormFu::Upload object, with a valid filehandle, but no Content-
       Length. This Constraint would still see this as a valid uploaded file - if you want to
       ensure that you get a file with content, instead use HTML::FormFu::Constraint::File::Size
       with min set to 1.
