Struct rsynth::backend::combined::TestAudioWriter

pub struct TestAudioWriter<'w, T, S> where
    T: AudioWriter<S>,
    S: Copy,  { /* fields omitted */ }

An audio writer, useful for testing.

Implementations

impl<'w, T, S> TestAudioWriter<'w, T, S> where
    T: AudioWriter<S>,
    S: Copy, 

pub fn new(writer: &'w mut T, expected_chunks: Vec<AudioChunk<S>>) -> Self

Create a new TestAudioWriter. The newly created will panic when the audio that is written to it does not match with expected_chunks.

Trait Implementations

impl<'w, T, S> AudioWriter<S> for TestAudioWriter<'w, T, S> where
    T: AudioWriter<S>,
    S: Debug + PartialEq + Copy, 

type Err = <T as AudioWriter<S>>::Err

The type of the error that occurs when reading data.

fn write_buffer(
    &mut self,
    chunk: &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.
