Trait Writer

pub trait Writer<S>: Send + Sync
where
    S: Sample,
{
    // Required methods
    fn sample_rate(&self) -> f64;
    fn num_channels(&self) -> usize;
    fn can_write(&self) -> bool;
    fn write_channel(
        &mut self,

}

Trait for writing audio data to files.

Implementations handle encoding and file format specifics. Call finalize when done to ensure proper file closure.

Required Methods

fn sample_rate(&self) -> f64

Get the sample rate of the writer.

fn num_channels(&self) -> usize

Get the number of channels of the writer.

fn can_write(&self) -> bool

Check whether the writer can write to audio an audio file. This is useful for particular audio files that use closing byte signatures, unlike WAV files which can usually be appended with more audio data at any time.

fn write_channel( &mut self, channel_index: usize, samples: &[S], ) -> Result<(), Box<dyn Error>>

Write samples to a specified channel.

fn finalize(&mut self) -> Result<(), Box<dyn Error>>

Finalize the writing of an audio file.
