impl Controller for MetricsController

fn is_matching(request: &Request, _connection: &ConnectionInfo) -> bool

Returns true if this controller should handle the given request. Called in declaration order; the first match wins.

fn process( _request: &Request, response: Response, _connection: &ConnectionInfo, ) -> Response

Produces the response. Receives the partially-built response (already populated with standard headers from [Header::get_header_list]) and must return it populated with a status code and body.
