Trait rsynth::backend::combined::AudioReader

pub trait AudioReader<S> where
    S: Copy, {
    type Err;
    fn number_of_channels(&self) -> usize;
    fn frames_per_second(&self) -> u64;
    fn fill_buffer(
        &mut self, 
        output: &mut AudioBufferOut<'_, '_, S>
    ) -> Result<usize, Self::Err>;
}

Define how audio is read.

This trait is generic over S, which represents the data-type used for a sample.

Associated Types

type Err

The type of the error that occurs when reading data.

Required methods

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.
