Struct gio::SocketClient

pub struct SocketClient { /* private fields */ }

GSocketClient is a lightweight high-level utility class for connecting to a network host using a connection oriented socket type.

You create a GSocketClient object, set any options you want, and then call a sync or async connect operation, which returns a SocketConnection subclass on success.

The type of the SocketConnection object returned depends on the type of the underlying socket that is in use. For instance, for a TCP/IP connection it will be a TcpConnection.

As GSocketClient is a lightweight object, you don’t need to cache it. You can just create a new one any time you need one.

Properties

enable-proxy

Enable proxy support.

Readable | Writeable | Construct

family

The address family to use for socket construction.

Readable | Writeable | Construct

local-address

The local address constructed sockets will be bound to.

Readable | Writeable | Construct

protocol

The protocol to use for socket construction, or 0 for default.

Readable | Writeable | Construct

proxy-resolver

The proxy resolver to use

Readable | Writeable | Construct

timeout

The I/O timeout for sockets, in seconds, or 0 for none.

Readable | Writeable | Construct

tls

Whether to create TLS connections.

Readable | Writeable | Construct

tls-validation-flags

The TLS validation flags used when creating TLS connections. The default value is TlsCertificateFlags::VALIDATE_ALL.

GLib guarantees that if certificate verification fails, at least one flag will be set, but it does not guarantee that all possible flags will be set. Accordingly, you may not safely decide to ignore any particular type of error. For example, it would be incorrect to mask TlsCertificateFlags::EXPIRED if you want to allow expired certificates, because this could potentially be the only error flag set even if other problems exist with the certificate. Therefore, there is no safe way to use this property. This is not a horrible problem, though, because you should not be attempting to ignore validation errors anyway. If you really must ignore TLS certificate errors, connect to the #GSocketClient::event signal, wait for it to be emitted with SocketClientEvent::TlsHandshaking, and use that to connect to #GTlsConnection::accept-certificate.

Signals

event

Emitted when @client’s activity on @connectable changes state. Among other things, this can be used to provide progress information about a network connection in the UI. The meanings of the different @event values are as follows:

• SocketClientEvent::Resolving: @client is about to look up @connectable in DNS. @connection will be None.

• SocketClientEvent::Resolved: @client has successfully resolved @connectable in DNS. @connection will be None.

• SocketClientEvent::Connecting: @client is about to make a connection to a remote host; either a proxy server or the destination server itself. @connection is the #GSocketConnection, which is not yet connected. Since GLib 2.40, you can access the remote address via g_socket_connection_get_remote_address().

• SocketClientEvent::Connected: @client has successfully connected to a remote host. @connection is the connected #GSocketConnection.

• SocketClientEvent::ProxyNegotiating: @client is about to negotiate with a proxy to get it to connect to @connectable. @connection is the #GSocketConnection to the proxy server.

• SocketClientEvent::ProxyNegotiated: @client has negotiated a connection to @connectable through a proxy server. @connection is the stream returned from g_proxy_connect(), which may or may not be a #GSocketConnection.

• SocketClientEvent::TlsHandshaking: @client is about to begin a TLS handshake. @connection is a #GTlsClientConnection.

• SocketClientEvent::TlsHandshaked: @client has successfully completed the TLS handshake. @connection is a #GTlsClientConnection.

• SocketClientEvent::Complete: @client has either successfully connected to @connectable (in which case @connection is the #GSocketConnection that it will be returning to the caller) or has failed (in which case @connection is None and the client is about to return an error).

Each event except SocketClientEvent::Complete may be emitted multiple times (or not at all) for a given connectable (in particular, if @client ends up attempting to connect to more than one address). However, if @client emits the #GSocketClient::event signal at all for a given connectable, then it will always emit it with SocketClientEvent::Complete when it is done.

Note that there may be additional #GSocketClientEvent values in the future; unrecognized @event values should be ignored.

Implements

SocketClientExt, [trait@glib::ObjectExt]

GLib type: GObject with reference counted clone semantics.

Implementations

impl SocketClient

pub const NONE: Option<&'static SocketClient> = None

pub fn new() -> SocketClient

Creates a new #GSocketClient with the default options.

Returns

a #GSocketClient. Free the returned object with g_object_unref().

Trait Implementations

impl Clone for SocketClient

fn clone(&self) -> Self

Makes a clone of this shared reference.

This increments the strong reference count of the object. Dropping the object will decrement it again.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SocketClient

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for SocketClient

fn default() -> Self

Returns the “default value” for a type.

impl HasParamSpec for SocketClient

type ParamSpec = ParamSpecObject

type SetValue = SocketClient

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(_: &str) -> ParamSpecObjectBuilder<'_, SocketClient>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for SocketClient

fn hash<H>(&self, state: &mut H)

where H: Hasher,

Hashes the memory address of this object.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for SocketClient

fn cmp(&self, other: &Self) -> Ordering

Comparison for two GObjects.

Compares the memory addresses of the provided objects.

fn max(self, other: Self) -> Self

where Self: Sized,

impl<OT: ObjectType> PartialEq<OT> for SocketClient

fn eq(&self, other: &OT) -> bool
