Used for emitting signals on Server::track_list_emit and LocalServer::track_list_emit, if T implements TrackListInterface or LocalTrackListInterface.

Variants

TrackListReplaced

Indicates that the entire tracklist has been replaced.

It is left up to the implementation to decide when a change to the track list is invasive enough that this signal should be emitted instead of a series of TrackAdded and TrackRemoved signals.

Fields

tracks: Vec<TrackId>

The new content of the tracklist.

current_track: TrackId

The identifier of the track to be considered as current.

/org/mpris/MediaPlayer2/TrackList/NoTrack indicates that there is no current track.

This should correspond to the mpris:trackid field of the Metadata property of the Player interface.

TrackAdded

Indicates that a track has been added to the track list.

Fields

metadata: Metadata

The metadata of the newly added item.

This must include a mpris:trackid entry.

after_track: TrackId

The identifier of the track after which the new track was inserted. The path /org/mpris/MediaPlayer2/TrackList/NoTrack indicates that the track was inserted at the start of the track list.

TrackRemoved

Indicates that a track has been removed from the track list.

Fields

track_id: TrackId

The identifier of the track being removed.

/org/mpris/MediaPlayer2/TrackList/NoTrack is not a valid value for this argument.

TrackMetadataChanged

Indicates that the metadata of a track in the tracklist has changed.

This may indicate that a track has been replaced, in which case the mpris:trackid metadata entry is different from the track_id argument.

Fields

track_id: TrackId

The id of the track which metadata has changed.

If the track id has changed, this will be the old value.

/org/mpris/MediaPlayer2/TrackList/NoTrack is not a valid value for this argument.

metadata: Metadata

The new track metadata.

This must include a mpris:trackid entry. If the track id has changed, this will be the new value.
