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".
