Struct nannou_audio::requester::Requester

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

A sound::Requester for converting backend audio requests into requests for buffers of a fixed size called from a separate thread.

The Requester works by calling fill_buffer with the requested buffer and sample rate from the audio backend each time the callback is invoked.

Methods

impl<S> Requester<S> where
    S: Sample, 

pub fn new(num_frames: usize, num_channels: usize) -> Self

Construct a new sound::Requester.

num_frames must be greater than 0.

pub fn fill_buffer<M, FA, FB>(
    &mut self,
    model: M,
    render: &Render<FA, FB>,
    output: &mut [S],
    channels: usize,
    sample_rate: u32
) -> M where
    FA: RenderFn<M, S>,
    FB: RenderResultFn<M, S>, 

Fill the given output buffer with samples requested from the model.

Panic!s if sample_rate is not greater than 0 or if the output buffer's length is not a multiple of the given number of channels.
