Struct rsynth::backend::combined::dummy::AudioDummy

pub struct AudioDummy<S> { /* fields omitted */ }

Dummy backend that does nothing, useful for testing and e.g. for offline renderers that have no audio input or output.

Implementations

impl<S> AudioDummy<S>

pub fn with_sample_rate_and_length(
    frames_per_second: u32,
    length_in_frames: usize
) -> Self

Create a new AudioDummy with the given sample rate, in frames per second.

pub fn new() -> Self

👎 Deprecated since 0.1.2:

Use with_sample_rate_and_length instead.

Create a new AudioDummy with the “default” sample rate of 44100 frames per second (CD quality) and a length of 0 samples.

Trait Implementations

impl<S> AudioReader<S> for AudioDummy<S> where
    S: Copy, 

type Err = Infallible

The type of the error that occurs when reading data.

fn number_of_channels(&self) -> usize

The number of audio channels that can be read.

fn frames_per_second(&self) -> u64

The sampling frequency in frames per second.

fn fill_buffer(
    &mut self,
    output: &mut AudioBufferOut<'_, '_, S>
) -> Result<usize, Self::Err>

Fill the buffers. Return the number of frames that have been read and written to the buffer. If the return value is < the number of frames in the input, no more frames can be expected.

impl<S> AudioWriter<S> for AudioDummy<S> where
    S: Copy, 

type Err = Infallible

The type of the error that occurs when reading data.

fn write_buffer(
    &mut self,
    _buffer: &AudioBufferIn<'_, '_, S>
) -> Result<(), Self::Err>

Write to the specified audio buffer.

fn specifies_number_of_channels(&self) -> bool

Return true if this AudioWriter is responsible for specifying the number of channels and false if this is determined by the first call to write_buffer.

fn number_of_channels(&self) -> usize

Return the number of channels. This method is only called if specifies_number_of_channels returns true. This method should always return the same number.
