Struct cubeb_backend::Stream

pub struct Stream(_);

Implementations

impl Stream

pub unsafe fn from_ptr(ptr: *mut cubeb_stream) -> Stream

Safety

This function is unsafe because it dereferences the given ptr pointer. The caller should ensure that pointer is valid.

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

Methods from Deref<Target = StreamRef>

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

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

Start playback.

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

Stop playback.

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

Trait Implementations

impl AsRef<StreamRef> for Stream

fn as_ref(&self) -> &StreamRef

Converts this type into a shared reference of the (usually inferred) input type.

impl Borrow<StreamRef> for Stream

fn borrow(&self) -> &StreamRef

Immutably borrows from an owned value.

impl Deref for Stream

type Target = StreamRef

The resulting type after dereferencing.

fn deref(&self) -> &StreamRef

Dereferences the value.

impl DerefMut for Stream

fn deref_mut(&mut self) -> &mut StreamRef

Mutably dereferences the value.

impl Drop for Stream

fn drop(&mut self)

Executes the destructor for this type.
