Trait Implementations

impl Default for AndroidAudioStreamSource

fn default() -> AndroidAudioStreamSource

Returns the “default value” for a type.

impl StreamSource for AndroidAudioStreamSource

fn new_playback_stream( &mut self, _num_channels: usize, _format: SampleFormat, _frame_rate: u32, _buffer_size: usize ) -> Result<(Box<dyn StreamControl>, Box<dyn PlaybackBufferStream>), BoxError>

Returns a stream control and buffer generator object. These are separate as the buffer generator might want to be passed to the audio stream.

fn new_async_playback_stream( &mut self, num_channels: usize, format: SampleFormat, frame_rate: u32, buffer_size: usize, _ex: &dyn AudioStreamsExecutor ) -> Result<(Box<dyn StreamControl>, Box<dyn AsyncPlaybackBufferStream>), BoxError>

Returns a stream control and async buffer generator object. These are separate as the buffer generator might want to be passed to the audio stream.

fn new_capture_stream( &mut self, _num_channels: usize, _format: SampleFormat, _frame_rate: u32, _buffer_size: usize, _effects: &[StreamEffect] ) -> Result<(Box<dyn StreamControl>, Box<dyn CaptureBufferStream>), BoxError>

Returns a stream control and buffer generator object. These are separate as the buffer generator might want to be passed to the audio stream. Default implementation returns NoopStreamControl and NoopCaptureStream.

fn new_async_capture_stream( &mut self, num_channels: usize, format: SampleFormat, frame_rate: u32, buffer_size: usize, _effects: &[StreamEffect], _ex: &dyn AudioStreamsExecutor ) -> Result<(Box<dyn StreamControl>, Box<dyn AsyncCaptureBufferStream>), BoxError>

Returns a stream control and async buffer generator object. These are separate as the buffer generator might want to be passed to the audio stream. Default implementation returns NoopStreamControl and NoopCaptureStream.

fn async_new_async_playback_stream<'life0, 'life1, 'async_trait>( &'life0 mut self, num_channels: usize, format: SampleFormat, frame_rate: u32, buffer_size: usize, ex: &'life1 dyn AudioStreamsExecutor ) -> Pin<Box<dyn Future<Output = Result<(Box<dyn StreamControl>, Box<dyn AsyncPlaybackBufferStream>), Box<dyn Error + Send + Sync>>> + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,

Returns a stream control and async buffer generator object asynchronously. Default implementation calls and blocks on new_async_playback_stream().

fn async_new_async_capture_stream<'life0, 'life1, 'life2, 'async_trait>( &'life0 mut self, num_channels: usize, format: SampleFormat, frame_rate: u32, buffer_size: usize, effects: &'life1 [StreamEffect], ex: &'life2 dyn AudioStreamsExecutor ) -> Pin<Box<dyn Future<Output = Result<(Box<dyn StreamControl>, Box<dyn AsyncCaptureBufferStream>), Box<dyn Error + Send + Sync>>> + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, Self: 'async_trait,

Returns a stream control and async buffer generator object asynchronously. Default implementation calls and blocks on new_async_capture_stream().

fn keep_rds(&self) -> Option<Vec<i32>>

Returns any open file descriptors needed by the implementor. The FD list helps users of the StreamSource enter Linux jails making sure not to close needed FDs.
