Enum MediaControlKind 

#[repr(C)]
pub enum MediaControlKind {
    SeekRelative = 0,
    SeekAbsolute = 1,
    OpenUri = 2,
    SetVolume = 3,
}

Holds the current session state and remembers whether the platform has been told about it.

Mirrors crate::haptics::HapticManager: the callback thread writes, the shell drains once per pass. The difference is that this is a LATEST-WINS value rather than a queue - a media widget wants the current track, not every track the app has ever played. What a control request from the platform’s media controls asks for (9h-i-a-i-a, 9h-i-a-i-b): everything a transport KEY cannot carry.

Variants

SeekRelative = 0

Move by position_us RELATIVE to the current position (MPRIS Seek; negative moves back). The app clamps to the track.

SeekAbsolute = 1

Jump to the ABSOLUTE position_us (MPRIS SetPosition, SMTC’s position change, MPChangePlaybackPositionCommand, onSeekTo).

OpenUri = 2

Open and play uri (MPRIS OpenUri). position_us is 0.

SetVolume = 3

Set the app’s output volume to volume (MPRIS Volume written; 0.0 silent, 1.0 full, above 1.0 is amplification a client may ask for and the app may clamp). The app applies it and publishes the result in NowPlayingInfo::volume.
