Implementations

impl DeviceSynchronousProxy

pub fn new(channel: Channel) -> Self

pub fn into_channel(self) -> Channel

pub fn wait_for_event(&self, deadline: Time) -> Result<DeviceEvent, 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 get_format( &self, ___deadline: Time ) -> Result<DeviceGetFormatResult, Error>

Returns the format selected by the client, or NO_RING_BUFFER if the client has not yet selected a ring buffer format.

pub fn get_gain(&self, ___deadline: Time) -> Result<DeviceGetGainResult, Error>

Returns the current gain state for this device.

pub fn get_buffer( &self, ___deadline: Time ) -> Result<DeviceGetBufferResult, Error>

Returns details about the ring buffer. Returns NO_RING_BUFFER if the client has not yet created the ring buffer.

pub fn set_notification_frequency( &self, notifications_per_ring: u32, ___deadline: Time ) -> Result<DeviceSetNotificationFrequencyResult, Error>

Overrides the position notification frequency for this stream. This affects the frequency of OnPositionNotify events only. It does not affect the frequency of notification events sent through the audio driver APIs.

pub fn get_position( &self, ___deadline: Time ) -> Result<DeviceGetPositionResult, Error>

Returns the current position (in bytes) within the ring buffer, along with the time (per MONOTONIC clock) that corresponds with that position. This can only be called after the ring buffer is established. Returns NOT_STARTED if the device has not yet Started streaming.

pub fn change_plug_state( &self, plug_change_time: i64, plugged: bool, ___deadline: Time ) -> Result<DeviceChangePlugStateResult, Error>

Hot-plugs or hot-unplugs an active virtual device, at the specified time.

pub fn adjust_clock_rate( &self, ppm_from_monotonic: i32, ___deadline: Time ) -> Result<DeviceAdjustClockRateResult, Error>

Immediately change the virtual device’s clock rate, as expressed in the timing and content of position notifications the driver emits. ‘ppm_monotonic’ cannot exceed [-1000,+1000]. Each rate change in rate is standalone; i.e. successive rate changes are not cumulative.
