SocketListener, SocketService

Required methods

fn accept<P: IsA<Cancellable>>(
    &self,
    cancellable: Option<&P>
) -> Result<(SocketConnection, Option<Object>), Error>

Blocks waiting for a client to connect to any of the sockets added to the listener. Returns a SocketConnection for the socket that was accepted.

If source_object is not None it will be filled out with the source object specified when the corresponding socket or address was added to the listener.

If cancellable is not None, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error IOErrorEnum::Cancelled will be returned.

source_object

location where gobject::Object pointer will be stored, or None

cancellable

optional Cancellable object, None to ignore.

Returns

a SocketConnection on success, None on error.

fn accept_socket<P: IsA<Cancellable>>(
    &self,
    cancellable: Option<&P>
) -> Result<(Socket, Option<Object>), Error>

Blocks waiting for a client to connect to any of the sockets added to the listener. Returns the Socket that was accepted.

If you want to accept the high-level SocketConnection, not a Socket, which is often the case, then you should use SocketListenerExt::accept instead.

If source_object is not None it will be filled out with the source object specified when the corresponding socket or address was added to the listener.

If cancellable is not None, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error IOErrorEnum::Cancelled will be returned.

source_object

location where gobject::Object pointer will be stored, or None.

cancellable

optional Cancellable object, None to ignore.

Returns

a Socket on success, None on error.

fn add_address<P: IsA<SocketAddress>, Q: IsA<Object>>(
    &self,
    address: &P,
    type_: SocketType,
    protocol: SocketProtocol,
    source_object: Option<&Q>
) -> Result<SocketAddress, Error>

Creates a socket of type type_ and protocol protocol, binds it to address and adds it to the set of sockets we're accepting sockets from.

Note that adding an IPv6 address, depending on the platform, may or may not result in a listener that also accepts IPv4 connections. For more deterministic behavior, see SocketListenerExt::add_inet_port.

source_object will be passed out in the various calls to accept to identify this particular source, which is useful if you're listening on multiple addresses and do different things depending on what address is connected to.

If successful and effective_address is non-None then it will be set to the address that the binding actually occurred at. This is helpful for determining the port number that was used for when requesting a binding to port 0 (ie: "any port"). This address, if requested, belongs to the caller and must be freed.

Call SocketListenerExt::close to stop listening on address; this will not be done automatically when you drop your final reference to self, as references may be held internally.

address

a SocketAddress

type_

a SocketType

protocol

a SocketProtocol

source_object

Optional gobject::Object identifying this source

effective_address

location to store the address that was bound to, or None.

Returns

true on success, false on error.

fn add_any_inet_port<P: IsA<Object>>(
    &self,
    source_object: Option<&P>
) -> Result<u16, Error>

Listens for TCP connections on any available port number for both IPv6 and IPv4 (if each is available).

This is useful if you need to have a socket for incoming connections but don't care about the specific port number.

source_object will be passed out in the various calls to accept to identify this particular source, which is useful if you're listening on multiple addresses and do different things depending on what address is connected to.

source_object

Optional gobject::Object identifying this source

Returns

the port number, or 0 in case of failure.

fn add_inet_port<P: IsA<Object>>(
    &self,
    port: u16,
    source_object: Option<&P>
) -> Result<(), Error>

Helper function for SocketListenerExt::add_address that creates a TCP/IP socket listening on IPv4 and IPv6 (if supported) on the specified port on all interfaces.

source_object will be passed out in the various calls to accept to identify this particular source, which is useful if you're listening on multiple addresses and do different things depending on what address is connected to.

Call SocketListenerExt::close to stop listening on port; this will not be done automatically when you drop your final reference to self, as references may be held internally.

port

an IP port number (non-zero)

source_object

Optional gobject::Object identifying this source

Returns

true on success, false on error.

fn add_socket<P: IsA<Socket>, Q: IsA<Object>>(
    &self,
    socket: &P,
    source_object: Option<&Q>
) -> Result<(), Error>

Adds socket to the set of sockets that we try to accept new clients from. The socket must be bound to a local address and listened to.

source_object will be passed out in the various calls to accept to identify this particular source, which is useful if you're listening on multiple addresses and do different things depending on what address is connected to.

The socket will not be automatically closed when the self is finalized unless the listener held the final reference to the socket. Before GLib 2.42, the socket was automatically closed on finalization of the self, even if references to it were held elsewhere.

socket

a listening Socket

source_object

Optional gobject::Object identifying this source

Returns

true on success, false on error.

fn close(&self)

Closes all the sockets in the listener.

fn set_backlog(&self, listen_backlog: i32)

Sets the listen backlog on the sockets in the listener. This must be called before adding any sockets, addresses or ports to the SocketListener (for example, by calling SocketListenerExt::add_inet_port) to be effective.

See SocketExt::set_listen_backlog for details

listen_backlog

an integer

fn get_property_listen_backlog(&self) -> i32

fn set_property_listen_backlog(&self, listen_backlog: i32)

fn connect_event<F: Fn(&Self, SocketListenerEvent, &Socket) + 'static>(
    &self,
    f: F
) -> SignalHandlerId

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.

Feature: v2_46

event

the event that is occurring

socket

the Socket the event is occurring on

fn connect_property_listen_backlog_notify<F: Fn(&Self) + 'static>(
    &self,
    f: F
) -> SignalHandlerId
