       "Net::Async::Tangence::Client" - connect to a "Tangence" server using "IO::Async"


       This subclass of Net::Async::Tangence::Protocol connects to a Tangence server, allowing
       the client program to access exposed objects in the server.  It is a concrete
       implementation of the "Tangence::Client" mixin.

       The following documentation concerns this specific implementation of the client; for more
       general information on the "Tangence"-specific parts of this class, see instead the
       documentation for Tangence::Client.


       The following named parameters may be passed to "new" or "configure":

       identity => STRING
               The identity string to send to the server.

       on_error => STRING or CODE
               Default error-handling policy for method calls. If set to either of the strings
               "carp" or "croak" then a CODE ref will be created that invokes the given function
               from "Carp"; otherwise must be a CODE ref.


       The following methods documented with a trailing call to "->get" return Future instances.

          $rootobj = $client->connect_url( $url, %args )->get

       Connects to a "Tangence" server at the given URL. The returned Future will yield the root
       object proxy once it has been obtained.

       Takes the following named arguments:

       on_registry => CODE
       on_root => CODE
               Invoked once the registry and root object proxies have been obtained from the
               server. See the documentation the Tangence::Client "tangence_connected" method.

       The following URL schemes are recognised:

       ·   exec

           Directly executes the server as a child process. This is largely provided for testing
           purposes, as the server will only run for this one client; it will exit when the
           client disconnects.


           The URL's path should point to the required command, and the query string will be
           split on "+" signs and used as the arguments. The authority section of the URL will be
           ignored, so may be left empty.

       ·   sshexec

           A convenient wrapper around the "exec" scheme, to connect to a server running remotely
           via ssh.


           The URL's authority section will give the SSH server (and optionally username), and
           the path and query sections will be used as for "exec".

           (This scheme is also available as "ssh", though this name is now deprecated)

       ·   tcp

           Connects to a server via a TCP socket.


           The URL's authority section will be used to give the server's hostname and port
           number. The other sections of the URL will be ignored.

       ·   unix

           Connects to a server via a UNIX local socket.


           The URL's path section will give the path to the local socket. The other sections of
           the URL will be ignored.

       ·   sshunix

           Connects to a server running remotely via a UNIX socket over ssh.


           (This is implemented by running perl remotely and sending it a tiny self-contained
           program that connects STDIN/STDOUT to the given UNIX socket path. It requires that the
           server has perl at least version 5.6 available in the path simply as "perl")
