pub struct SocketService { /* private fields */ }
Expand description
A GSocketService
is an object that represents a service that
is provided to the network or over local sockets. When a new
connection is made to the service the incoming
signal is emitted.
A GSocketService
is a subclass of SocketListener
and you need
to add the addresses you want to accept connections on with the
SocketListener
APIs.
There are two options for implementing a network service based on
GSocketService
. The first is to create the service using
new()
and to connect to the
incoming
signal. The second is to subclass
GSocketService
and override the default signal handler implementation.
In either case, the handler must immediately return, or else it
will block additional incoming connections from being serviced.
If you are interested in writing connection handlers that contain
blocking code then see ThreadedSocketService
.
The socket service runs on the main loop of the
thread-default context (see
[glib::MainContext::push_thread_default()
][crate::glib::MainContext::push_thread_default()]) of the thread it is
created in, and is not threadsafe in general. However, the calls to start and
stop the service are thread-safe so these can be used from threads that
handle incoming clients.
§Properties
§active
Whether the service is currently accepting connections.
Readable | Writeable | Construct
SocketListener
§listen-backlog
The number of outstanding connections in the listen queue.
Readable | Writeable | Construct
§Signals
§incoming
The ::incoming signal is emitted when a new incoming connection to @service needs to be handled. The handler must initiate the handling of @connection, but may not block; in essence, asynchronous operations must be used.
@connection will be unreffed once the signal handler returns, so you need to ref it yourself if you are planning to use it.
SocketListener
§event
Emitted when @listener’s activity on @socket changes state. Note that when @listener is used to listen on both IPv4 and IPv6, a separate set of signals will be emitted for each, and the order they happen in is undefined.

Implementations§
source§impl SocketService
impl SocketService
pub const NONE: Option<&'static SocketService> = None
sourcepub fn new() -> SocketService
pub fn new() -> SocketService
Creates a new #GSocketService with no sockets to listen for. New listeners can be added with e.g. g_socket_listener_add_address() or g_socket_listener_add_inet_port().
New services are created active, there is no need to call g_socket_service_start(), unless g_socket_service_stop() has been called before.
§Returns
a new #GSocketService.
