TITLE

Plack::Middleware::Return::MultiLevel::Utils - Ease of Use Utility subroutines

SYNOPSIS

use Plack::Middleware::Return::MultiLevel::Utils
  qw/return_to_level return_to_default_level/;

return_to_default_level($env,
  [200, ['Content-Type', 'text/plain'], ['default']]);

return_to_level($env, 'set_level_name',
  [200, ['Content-Type', 'text/plain'], ['named level']]);

DESCRIPTION

Ideally you'd invoke your Return::MultiLevel return points via one if these importable subroutines, rather than reaching into the psgi_env hash. This gives you better encapsulation and allows the underlying code to change without busted your use.

EXPORTS

This class defines the following exportable subroutines

return_to_default_level

return_to_default_level($env,
  [200, ['Content-Type', 'text/plain'], ['default']]);

Requires $psgi_env and a response, which typically is a PSGI type response, athough you can return anything you want if there is middleware to convert it to an acceptable PSGI style response, for example.

This can also be imported and called as a method on an object that does the env method. For example:

$catalyst_context->request->return_to_default_level(\@response);

return_to_level

return_to_level($env, 'set_level_name',
  [200, ['Content-Type', 'text/plain'], ['named level']]);

Just like "return_to_default_level" except that the second argument is the name of a return level that you set. Also can be called as a method against an object that does env.
