Enum AbsoluteVolumeHandlerRequest

pub enum AbsoluteVolumeHandlerRequest {
    SetVolume {
        requested_volume: u8,
        responder: AbsoluteVolumeHandlerSetVolumeResponder,
    },
    OnVolumeChanged {
        responder: AbsoluteVolumeHandlerOnVolumeChangedResponder,
    },
    GetCurrentVolume {
        responder: AbsoluteVolumeHandlerGetCurrentVolumeResponder,
    },
}

Handler for absolute volume requests from a remote peer. See AVRCP v 1.6.2 section 6.13.2. Absolute volume is represented as a percentage using one byte with the most significant bit reserved. 0% is represented as 0x0 and 100% as 0x7f. Volume should scaled between the two values.

Variants

SetVolume

Requests that the absolute volume of the player be changed. requested_volume is the requested volume by the peer. Returns the actual volume set locally by the handler.

Fields

requested_volume: u8

responder: AbsoluteVolumeHandlerSetVolumeResponder

OnVolumeChanged

Returns latest volume of the handler to the AVRCP service. This function should return immediately on the first call and if the volume has changed since the last call to this function, otherwise it should only return when the volume has been changed. Multiple outstanding OnVolumeChanged requests can be made - all outstanding calls will return when the volume has been changed.

Fields

responder: AbsoluteVolumeHandlerOnVolumeChangedResponder

GetCurrentVolume

Returns the current volume immediately.

Fields

responder: AbsoluteVolumeHandlerGetCurrentVolumeResponder
