Struct MprisPoller 

pub struct MprisPoller {
    state: Arc<Mutex<MprisSnapshot>>,
    stop: Arc<AtomicBool>,
}

Background MPRIS2 progress reader.

Polling on a dedicated thread avoids the per-frame D-Bus latency (a couple ms per round-trip on a quiet desktop, much worse if a player is slow to respond). The engine consumes the snapshot through MprisPoller::snapshot each frame; the call is a cheap Mutex lock + clone.

Fields

state: Arc<Mutex<MprisSnapshot>>

stop: Arc<AtomicBool>

Implementations

impl MprisPoller

pub fn spawn() -> Option<Self>

Spawn the background poller. Returns None when the D-Bus session bus isn’t reachable (headless CI, sandbox without bus access, …) so the caller can fall back to the local-window progress instead of paying for a poller that will never produce a useful snapshot.

pub fn snapshot(&self) -> MprisSnapshot

Current snapshot. Cheap (mutex lock + clone, no D-Bus traffic).

Trait Implementations

impl Drop for MprisPoller

fn drop(&mut self)

Executes the destructor for this type.
