Provided Methods

fn close(&self) -> Result<(), LoggableError>

close the device

fn delay(&self) -> u32

the number of frames queued in the device

fn open(&self) -> Result<(), LoggableError>

open the device with the specified caps

fn prepare(&self, spec: &mut AudioRingBufferSpec) -> Result<(), LoggableError>

configure device with format

fn unprepare(&self) -> Result<(), LoggableError>

undo the configuration

fn read( &self, audio_data: &mut [u8], ) -> Result<(u32, Option<ClockTime>), LoggableError>

Read samples from the device.

Returns

timestamp

a GstClockTime

fn reset(&self)

unblock a read to the device and reset.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
