Detailed Description

C_ATTR(foo, :Local :ActionClass(REST))
void foo(Context *c); // do setup for HTTP method specific handlers
C_ATTR(foo_GET, :Private)
void foo_GET(Context *c); // do something for GET requests
C_ATTR(foo_PUT, :Private)
void foo_PUT(Context *c); // do something for PUT requests

This Action handles doing automatic method dispatching for REST requests. It takes a normal Cutelyst action, and changes the dispatch to append an underscore and method name. First it will try dispatching to an action with the generated name, and failing that it will try to dispatch to a regular method.

For example, in the synopsis above, calling GET on "/foo" would result in the foo_GET method being dispatched.

If a method is requested that is not implemented, this action will return a status 405 (Method Not Found). It will populate the "Allow" header with the list of implemented request methods. You can override this behavior by implementing a custom 405 handler like so:

C_ATTR(foo_not_implemented, :Private)
void foo_not_implemented(Context *c); // handle not implemented methods

If you do not provide an _OPTIONS method, we will automatically respond with a 200 OK. The "Allow" header will be populated with the list of implemented request methods. If you do not provide an _HEAD either, we will auto dispatch to the _GET one in case it exists.
