Required Methods§

source

fn export( &self, connection: &DBusConnection, object_path: &str ) -> Result<(), Error>

Exports self at object_path on connection.

This can be called multiple times to export the same self onto multiple connections however the object_path provided must be the same for all connections.

Use unexport() to unexport the object.

connection

A DBusConnection to export self on.

object_path

The path to export the interface at.

Returns

true if the interface was exported on connection, otherwise false with error set.

source

fn flush(&self)

If self has outstanding changes, request for these changes to be emitted immediately.

For example, an exported D-Bus interface may queue up property changes and emit the org.freedesktop.DBus.Properties.PropertiesChanged signal later (e.g. in an idle handler). This technique is useful for collapsing multiple property changes into one.

source

fn connection(&self) -> Option<DBusConnection>

Gets the first connection that self is exported on, if any.

Returns

A DBusConnection or None if self is not exported anywhere. Do not free, the object belongs to self.

source

fn connections(&self) -> Vec<DBusConnection>

Gets a list of the connections that self is exported on.

Returns

A list of all the connections that self is exported on. The returned list should be freed with g_list_free() after each element has been freed with g_object_unref().

source

fn flags(&self) -> DBusInterfaceSkeletonFlags

Gets the DBusInterfaceSkeletonFlags that describes what the behavior of self

Returns

One or more flags from the DBusInterfaceSkeletonFlags enumeration.

source

fn info(&self) -> DBusInterfaceInfo

Gets D-Bus introspection information for the D-Bus interface implemented by self.

Returns

A DBusInterfaceInfo (never None). Do not free.

source

fn object_path(&self) -> Option<GString>

Gets the object path that self is exported on, if any.

Returns

A string owned by self or None if self is not exported anywhere. Do not free, the string belongs to self.

source

fn properties(&self) -> Variant

Gets all D-Bus properties for self.

Returns

A glib::Variant of type [‘a{sv}’][G-VARIANT-TYPE-VARDICT:CAPS]. Free with g_variant_unref().

source

fn has_connection(&self, connection: &DBusConnection) -> bool

Checks if self is exported on connection.

connection

A DBusConnection.

Returns

true if self is exported on connection, false otherwise.

source

fn set_flags(&self, flags: DBusInterfaceSkeletonFlags)

Sets flags describing what the behavior of skeleton should be.

flags

Flags from the DBusInterfaceSkeletonFlags enumeration.

source

fn unexport(&self)

Stops exporting self on all connections it is exported on.

To unexport self from only a single connection, use unexport_from_connection()

source

fn unexport_from_connection(&self, connection: &DBusConnection)

Stops exporting self on connection.

To stop exporting on all connections the interface is exported on, use unexport().

connection

A DBusConnection.

source

fn g_flags(&self) -> DBusInterfaceSkeletonFlags

Flags from the DBusInterfaceSkeletonFlags enumeration.

source

fn set_g_flags(&self, g_flags: DBusInterfaceSkeletonFlags)

Flags from the DBusInterfaceSkeletonFlags enumeration.

source

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

Emitted when a method is invoked by a remote caller and used to determine if the method call is authorized.

Note that this signal is emitted in a thread dedicated to handling the method call so handlers are allowed to perform blocking IO. This means that it is appropriate to call e.g. polkit_authority_check_authorization_sync() with the POLKIT_CHECK_AUTHORIZATION_FLAGS_ALLOW_USER_INTERACTION flag set.

If false is returned then no further handlers are run and the signal handler must take a reference to invocation and finish handling the call (e.g. return an error via g_dbus_method_invocation_return_error()).

Otherwise, if true is returned, signal emission continues. If no handlers return false, then the method is dispatched. If interface has an enclosing GDBusObjectSkeleton, then the GDBusObjectSkeleton::authorize-method signal handlers run before the handlers for this signal.

The default class handler just returns true.

Please note that the common case is optimized: if no signals handlers are connected and the default class handler isn’t overridden (for both interface and the enclosing GDBusObjectSkeleton, if any) and property::DBusInterfaceSkeleton::g-flags does not have the DBusInterfaceSkeletonFlags::HANDLE_METHOD_INVOCATIONS_IN_THREAD flags set, no dedicated thread is ever used and the call will be handled in the same thread as the object that interface belongs to was exported in.

invocation

A DBusMethodInvocation.

Returns

true if the call is authorized, false otherwise.

source

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