Struct pris::EventManager

pub struct EventManager<'a> { /* private fields */ }

A struct that simplifies the process of adding and removing listeners and callbacks to/from MPRIS DBus signals.

Implementations

impl EventManager<'_>

pub fn new(conn: &SyncConnection) -> EventManager<'_>

Creates a new event manager.

pub async fn add_callback<F>(
    &mut self,
    event_type: EventType,
    callback: F
) -> Result<MsgMatch, Box<dyn Error>> where
    F: FnMut(Message) -> bool + Send + 'static, 

Adds a new callback to the event manager.

Callbacks can be provided either as a closure, or as a function. A callback takes only one parameter, a Message.

Errors

Returns an Err if there is a failure in adding a match rule to the connection.

Example

let mut manager = EventManager::new(&connection);
// Be advised that it is important that this is assigned to a variable
let _incoming = manager
    .add_callback(EventType::PropertiesChanged, |msg| {
        println!("Data: {:?}", msg);
        true
    })
    .await?;

pub async fn clear_callbacks(&mut self) -> Result<(), Box<dyn Error>>

Clears all registered callbacks from the manager.

Errors

Returns an Err if there is a failure in removing a match from the connection.
