Implementations

impl<'c> SessionsNodeProxyBlocking<'c>

pub fn new(conn: &Connection) -> Result<SessionsNodeProxyBlocking<'c>>

Creates a new proxy with the default service and path.

pub fn builder(conn: &Connection) -> ProxyBuilder<'c, Self>

Returns a customizable builder for this proxy.

pub fn into_inner(self) -> Proxy<'c>

Consumes self, returning the underlying zbus::Proxy.

pub fn inner(&self) -> &Proxy<'c>

The reference to the underlying zbus::Proxy.

pub fn access_grant(&self, uid: u32) -> Result<()>

AccessGrant method

By default, only the user ID (UID) who created the session have access to it. This method used to grant other users access to this session.

Arguments

• uid - The UID to the user account which is granted access;

pub fn access_revoke(&self, uid: u32) -> Result<()>

AccessRevoke method

This revokes access to a session object for a specific user. Please note that the owner (the user which initiated this session) cannot have its access revoked.

Arguments

• uid - The UID to the user account which gets the access revoked.

pub fn connect(&self) -> Result<()>

Connect method

This method starts the connection process. This requires that all credentials needed before contacting the server have been provided. It is always a good idea to first call the net.openvpn.v3.sessions.Ready method first to ensure the backend is ready to connect.

pub fn disconnect(&self) -> Result<()>

Disconnect method

Disconnects a VPN connection. This will shutdown and stop the VPN backend process and the session object will be removed.

pub fn log_forward(&self, enable: bool) -> Result<()>

LogForward method

This enables log forwarding from the session to the currently connected D-Bus client. The forwarding itself is sent by the net.openvpn.v3.log service.

Arguments

• enable - Enables or disables the log forwarding.

pub fn pause(&self, reason: &str) -> Result<()>

Pause method

This method pauses an on-going VPN connection.

Arguments

• reason - A string used for log purposes primarily, describing why the tunnel was paused.

pub fn ready(&self) -> Result<()>

Ready method

This method is to check if the backend VPN client is ready to connect. If it is ready, it will return immediately. If it is not, it will return with a D-Bus error exception providing the reason it is not ready. Most commonly it needs some input from the user, such as user credentials or some challenge token not already provided in the configuration.

pub fn restart(&self) -> Result<()>

Restart method

Completely disconnects and reconnects an active VPN connection.

pub fn resume(&self) -> Result<()>

Resume method

Resumes a paused VPN connection.

pub fn cached_property<T>( &self, property_name: &str, ) -> Result<Option<T>, Error>

where T: TryFrom<OwnedValue>, <T as TryFrom<OwnedValue>>::Error: Into<Error>,

Get the cached value of the property property_name.

This returns None if the property is not in the cache. This could be because the cache was invalidated by an update, because caching was disabled for this property or proxy, or because the cache has not yet been populated. Use get_property to fetch the value from the peer.

pub fn cached_property_raw<'p>( &'p self, property_name: &'p str, ) -> Option<impl Deref<Target = Value<'static>> + 'p>

Get the cached value of the property property_name.

Same as cached_property, but gives you access to the raw value stored in the cache. This is useful if you want to avoid allocations and cloning.

pub fn get_property<T>(&self, property_name: &str) -> Result<T, Error>

where T: TryFrom<OwnedValue>, <T as TryFrom<OwnedValue>>::Error: Into<Error>,

Get the property property_name.

Get the property value from the cache or call the Get method of the org.freedesktop.DBus.Properties interface.

pub fn set_property<'t, T>( &self, property_name: &str, value: T, ) -> Result<(), Error>

where T: 't + Into<Value<'t>>,

Set the property property_name.

Effectively, call the Set method of the org.freedesktop.DBus.Properties interface.

pub fn call_method<'m, M, B>( &self, method_name: M, body: &B, ) -> Result<Arc<Message>, Error>

where M: TryInto<MemberName<'m>>, <M as TryInto<MemberName<'m>>>::Error: Into<Error>, B: Serialize + DynamicType,

Call a method and return the reply.

Typically, you would want to use call method instead. Use this method if you need to deserialize the reply message manually (this way, you can avoid the memory allocation/copying, by deserializing the reply to an unowned type).

pub fn call<'m, M, B, R>(&self, method_name: M, body: &B) -> Result<R, Error>

where M: TryInto<MemberName<'m>>, <M as TryInto<MemberName<'m>>>::Error: Into<Error>, B: Serialize + DynamicType, R: DeserializeOwned + Type,

Call a method and return the reply body.

Use call_method instead if you need to deserialize the reply manually/separately.

pub fn call_with_flags<'m, M, B, R>( &self, method_name: M, flags: BitFlags<MethodFlags>, body: &B, ) -> Result<Option<R>, Error>

where M: TryInto<MemberName<'m>>, <M as TryInto<MemberName<'m>>>::Error: Into<Error>, B: Serialize + DynamicType, R: DeserializeOwned + Type,

Call a method and return the reply body, optionally supplying a set of method flags to control the way the method call message is sent and handled.

Use call instead if you do not need any special handling via additional flags. If the NoReplyExpected flag is passed , this will return None immediately after sending the message, similar to call_noreply

pub fn call_noreply<'m, M, B>( &self, method_name: M, body: &B, ) -> Result<(), Error>

where M: TryInto<MemberName<'m>>, <M as TryInto<MemberName<'m>>>::Error: Into<Error>, B: Serialize + DynamicType,

where M: TryInto<MemberName<'m>>, <M as TryInto<MemberName<'m>>>::Error: Into<Error>,

Create a stream for signal named signal_name.

Errors

Apart from general I/O errors that can result from socket communications, calling this method will also result in an error if the destination service has not yet registered its well-known name with the bus (assuming you’re using the well-known name as destination).

pub fn receive_signal_with_args<'m, M>( &self, signal_name: M, args: &[(u8, &str)], ) -> Result<SignalIterator<'m>, Error>

where M: TryInto<MemberName<'m>>, <M as TryInto<MemberName<'m>>>::Error: Into<Error>,

Same as Proxy::receive_signal but with a filter.

The D-Bus specification allows you to filter signals by their arguments, which helps avoid a lot of unnecessary traffic and processing since the filter is run on the server side. Use this method where possible. Note that this filtering is limited to arguments of string types.

The arguments are passed as a tuples of argument index and expected value.

pub fn receive_all_signals(&self) -> Result<SignalIterator<'static>, Error>

Create a stream for all signals emitted by this service.

Errors

Apart from general I/O errors that can result from socket communications, calling this method will also result in an error if the destination service has not yet registered its well-known name with the bus (assuming you’re using the well-known name as destination).

pub fn receive_property_changed<'name, T>( &self, name: &'name str, ) -> PropertyIterator<'a, T>

where 'name: 'a,

Get an iterator to receive owner changed events.

If the proxy destination is a unique name, the stream will be notified of the peer disconnection from the bus (with a None value).

If the proxy destination is a well-known name, the stream will be notified whenever the name owner is changed, either by a new peer being granted ownership (Some value) or when the name is released (with a None value).

Note that zbus doesn’t queue the updates. If the listener is slower than the receiver, it will only receive the last update.

pub fn receive_owner_changed(&self) -> Result<OwnerChangedIterator<'_>, Error>

Get an iterator to receive property changed events.

Note that zbus doesn’t queue the updates. If the listener is slower than the receiver, it will only receive the last update.

pub fn inner(&self) -> &Proxy<'a>

Get a reference to the underlying async Proxy.
