HTML::FormFu::Constraint::File - File Upload Constraint
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.
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.
Is a sub-class of, and inherits methods from HTML::FormFu::Constraint
