Provided Methods§

Source

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

close the device

Source

fn delay(&self) -> u32

the number of frames queued in the device

Source

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

open the device with the specified caps

Source

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

configure device with format

Source

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

undo the configuration

Source

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

Read samples from the device.

§Returns
§timestamp

a GstClockTime

Source

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.
