Implementations

impl HeadsetGainSynchronousProxy

pub fn new(channel: Channel) -> Self

pub fn into_channel(self) -> Channel

pub fn wait_for_event( &self, deadline: MonotonicInstant, ) -> Result<HeadsetGainEvent, Error>

Waits until an event arrives and returns it. It is safe for other threads to make concurrent requests while waiting for an event.

pub fn set_speaker_gain(&self, requested: u8) -> Result<(), Error>

Make a request to the headset to set the speaker gain to requested.

requested must be in the range [0-15] inclusive. Any values outside of this range will result in the channel closing with a ZX_ERR_INVALID_ARGUMENT epitaph.

pub fn watch_speaker_gain( &self, ___deadline: MonotonicInstant, ) -> Result<u8, Error>

Hanging get to watch for updates to the headset speaker gain. Responses represent the current gain value that is set.

The returned gain value will always be in the range [0-15] inclusive.

pub fn set_microphone_gain(&self, requested: u8) -> Result<(), Error>

Make a request to the Headset to set the microphone gain to requested.

requested must be in the range [0-15] inclusive. Any values outside of this range will result in the channel closing with a ZX_ERR_INVALID_ARGUMENT epitaph.

pub fn watch_microphone_gain( &self, ___deadline: MonotonicInstant, ) -> Result<u8, Error>

Hanging get to watch for updates to the headset microphone gain. Responses represent the current gain value that is set.

The returned gain value will always be in the range [0-15] inclusive.
