Struct LocalDBusSource

pub struct LocalDBusSource<Data: 'static> { /* private fields */ }

A event source conncetion to D-Bus, thread local + non-async version

Implementations

impl<Data> LocalDBusSource<Data>

pub fn new_session() -> Result<(Self, Sender<Message>)>

Create a new connection to the session bus.

pub fn new_system() -> Result<(Self, Sender<Message>)>

Create a new connection to the system-wide bus.

pub fn unique_name(&self) -> BusName<'_>

Get the connection’s unique name.

It’s usually something like “:1.54”

pub fn with_proxy<'a, 'b, Dest: Into<BusName<'a>>, BusPath: Into<Path<'a>>>( &'b self, dest: Dest, path: BusPath, timeout: Duration, ) -> Proxy<'a, &'b Self>

pub fn request_name<'a, Name: Into<BusName<'a>>>( &self, name: Name, allow_replacement: bool, replace_existing: bool, do_not_queue: bool, ) -> Result<RequestNameReply, Error>

Request a name on the D-Bus.

For detailed information on the flags and return values, see the libdbus documentation.

pub fn release_name<'a, Name: Into<BusName<'a>>>( &self, name: Name, ) -> Result<ReleaseNameReply, Error>

Release a previously requested name on the D-Bus.

pub fn add_match<Args: ReadAll, Callback>( &self, match_rule: MatchRule<'static>, callback: Callback, ) -> Result<Token, Error>

where Callback: FnMut(Args, &Self, &Message) -> bool + 'static,

Adds a new match to the connection, and sets up a callback when this message arrives.

The returned value can be used to remove the match. The match is also removed if the callback returns “false”.

pub fn add_match_data<Args: ReadAll, Callback>( &self, match_rule: MatchRule<'static>, callback: Callback, ) -> Result<Token, Error>

where Callback: FnMut(Args, &Self, &Message, &mut Data) -> bool + 'static,

Adds a new match to the connection, and sets up a callback when this message arrives. This callback will be able to access the calloop user data.

The returned value can be used to remove the match. The match is also removed if the callback returns “false”.

pub fn remove_match(&self, id: Token) -> Result<(), Error>

Removes a previously added match and callback from the connection.

pub fn process(&mut self, timeout: Duration) -> Result<bool, Error>

pub fn channel(&self) -> &Channel

The Channel for this connection

pub fn quick_insert( self, handle: LoopHandle<Data>, panic_on_orphan: bool, ) -> Result<Source<LocalDBusSource<Data>>, InsertError<LocalDBusSource<Data>>>

Insert this source into the given event loop with an adapder that ether panics on orphan events or just logs it at warn level. You probably only what this if you set eavesdrop on a MatchRule.

Trait Implementations

impl<Data> BlockingSender for LocalDBusSource<Data>

fn send_with_reply_and_block( &self, msg: Message, timeout: Duration, ) -> Result<Message, Error>
