Implementations§

source§

impl CodecSynchronousProxy

source

pub fn new(channel: Channel) -> Self

source

pub fn into_channel(self) -> Channel

source

pub fn wait_for_event(&self, deadline: Time) -> Result<CodecEvent, Error>

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

source

pub fn get_health_state(&self, ___deadline: Time) -> Result<HealthState, Error>

Retrieves top level health state. A driver not responding promptly can be used as an indication of an unhealthy driver.

source

pub fn signal_processing_connect( &self, protocol: ServerEnd<SignalProcessingMarker> ) -> Result<(), Error>

Connect to a SignalProcessing protocol. Multiple connections may be supported, if a new connection request is not supported, i.e. the maximum number of connections have already been created, for instance one, then the protocol channel (not the channel upon which SignalProcessingConnect is being called) will be closed with a ZX_ERR_ALREADY_BOUND epitaph. If signal processing is not supported at all, then the protocol channel (again, not the channel upon which SignalProcessingConnect is being called) will be closed with a ZX_ERR_NOT_SUPPORTED epitaph. This method is named SignalProcessingConnect instead of Connect because this protocol is intended to be composed, and hence the more verbose name allows differentiation and improved clarity.

source

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

Resets the codec. Reset returns when the reset is completed. If the driver can’t successfully reset the codec it will close the codec protocol channel, in this case the client may obtain a new codec protocol channel and retry.

source

pub fn get_properties( &self, ___deadline: Time ) -> Result<CodecProperties, Error>

Retrieves top level static properties.

source

pub fn stop(&self, ___deadline: Time) -> Result<i64, Error>

Stops the codec operation. Stop returns when configuring the codec to stop is completed. This method does not wait for the hardware to actually stop playback/capture (i.e. turn_off_delay impact is not taken into account), nor is any such delay reflected in the returned stop_time. stop_time indicates when the driver finished configuring the codec to stop, as measured in the CLOCK_MONOTONIC timeline. If the driver cannot successfully configure the codec to stop, it will close the codec protocol channel, in which case the client may obtain a new codec protocol channel and retry.

source

pub fn start(&self, ___deadline: Time) -> Result<i64, Error>

Start/Re-start the codec operation. Start returns when configuring the codec to start is completed. This method does not wait for the hardware to actually start playback/capture (i.e. turn_on_delay impact is not taken into account), nor is any such delay reflected in the returned start_time. start_time indicates when the driver finished configuring the codec to start, as measured in the CLOCK_MONOTONIC timeline. If the driver can’t successfully start the codec, it will close the codec protocol channel, in which case the client may obtain a new codec protocol channel and retry.

source

pub fn is_bridgeable(&self, ___deadline: Time) -> Result<bool, Error>

Returns whether a codec is bridgeable.

source

pub fn set_bridged_mode(&self, enable_bridged_mode: bool) -> Result<(), Error>

Sets a codec’s bridged mode. This method is required, but it only needs to take action if the codec supports bridged mode as specified by its reply to IsBridgeable.

source

pub fn get_dai_formats( &self, ___deadline: Time ) -> Result<CodecGetDaiFormatsResult, Error>

Retrieves the DAI formats supported by the codec, if not available at the time the codec may reply with an error status and the controller may retry at a later time. Retrieving multiple DaiSupportedFormats allows for cases where exclusive combinations of the parameters in DaiSupportedFormats may be supported.

source

pub fn set_dai_format( &self, format: &DaiFormat, ___deadline: Time ) -> Result<CodecSetDaiFormatResult, Error>

Sets the DAI format to be used in the interface between the controller and codec. Returns an error if not supported at the time of the request (e.g. for removable hardware).

source

pub fn watch_plug_state(&self, ___deadline: Time) -> Result<PlugState, Error>

Get the plug detect state via a hanging get. The driver will reply to the first WatchPlugState sent by the client. The driver will not respond to subsequent client WatchPlugState calls until the plug state changes from what was most recently reported.
