Struct cubeb_backend::StreamRef

pub struct StreamRef(_);

Implementations

impl StreamRef

pub fn start(&self) -> Result<(), Error>

Start playback.

pub fn stop(&self) -> Result<(), Error>

Stop playback.

pub fn reset_default_device(&self) -> Result<(), Error>

Reset stream to the default device.

pub fn position(&self) -> Result<u64, Error>

Get the current stream playback position.

pub fn latency(&self) -> Result<u32, Error>

Get the latency for this stream, in frames. This is the number of frames between the time cubeb acquires the data in the callback and the listener can hear the sound.

pub fn input_latency(&self) -> Result<u32, Error>

Get the input latency for this stream, in frames. This is the number of frames between the time the audio input device records the audio, and the cubeb callback delivers it. This returns an error if the stream is output-only.

pub fn set_volume(&self, volume: f32) -> Result<(), Error>

Set the volume for a stream.

pub fn set_name(&self, name: &CStr) -> Result<(), Error>

Change a stream's name

pub fn current_device(&self) -> Result<&DeviceRef, Error>

Get the current output device for this stream.

pub fn device_destroy(&self, device: DeviceRef) -> Result<(), Error>

Destroy a cubeb_device structure.

pub fn register_device_changed_callback(
    &self,
    callback: Option<unsafe extern "C" fn(*mut c_void)>
) -> Result<(), Error>

Set a callback to be notified when the output device changes.

pub fn user_ptr(&self) -> *mut c_void

impl StreamRef

pub unsafe fn from_ptr<'a>(ptr: *mut cubeb_stream) -> &'a StreamRef

pub unsafe fn from_ptr_mut<'a>(ptr: *mut cubeb_stream) -> &'a mut StreamRef

pub fn as_ptr(&self) -> *mut cubeb_stream

Trait Implementations

impl AsRef<StreamRef> for Stream

fn as_ref(&self) -> &StreamRef

Performs the conversion.

impl Borrow<StreamRef> for Stream

fn borrow(&self) -> &StreamRef

Immutably borrows from an owned value.

impl Debug for StreamRef

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.
