Struct VioSShmStreamSource

pub struct VioSShmStreamSource {
    vios_client: Arc<Mutex<VioSClient>>,
    stream_descs: Vec<StreamDesc>,
}

Adapter that provides the ShmStreamSource trait around the VioS backend.

Fields

vios_client: Arc<Mutex<VioSClient>>

stream_descs: Vec<StreamDesc>

Implementations

impl VioSShmStreamSource

pub fn new<P: AsRef<Path>>(server: P) -> Result<VioSShmStreamSource, Error>

Creates a new stream source given the path to the audio server’s socket.

impl VioSShmStreamSource

fn new_stream_inner( &mut self, stream_id: u32, direction: StreamDirection, num_channels: usize, format: SampleFormat, frame_rate: u32, buffer_size: usize, _effects: &[StreamEffect], client_shm: &dyn AudioSharedMemory<Error = Error>, _buffer_offsets: [u64; 2], ) -> Result<Box<dyn ShmStream>, BoxError>

fn get_unused_stream_id(&self, direction: StreamDirection) -> Option<u32>

Trait Implementations

impl ShmStreamSource<Error> for VioSShmStreamSource

fn new_stream( &mut self, direction: StreamDirection, num_channels: usize, format: SampleFormat, frame_rate: u32, buffer_size: usize, effects: &[StreamEffect], client_shm: &dyn AudioSharedMemory<Error = Error>, buffer_offsets: [u64; 2], ) -> Result<Box<dyn ShmStream>, BoxError>

Creates a new stream

fn keep_fds(&self) -> Vec<RawDescriptor>

Get a list of file descriptors used by the implementation.

Returns any open file descriptors needed by the implementation. This list helps users of the ShmStreamSource enter Linux jails without closing needed file descriptors.
