Enum InputSource 

pub enum InputSource {
    Silence,
    Constant(f32),
    Buffer(Vec<Vec<f32>>),
    Generator(Box<dyn FnMut(usize, f64) -> f32>),
}

What audio gets fed into the plugin’s input bus each block.

Silence is the default. Effects with smoothers / lookahead / modulators usually want one of the non-silent variants to reach steady state during the run.

Variants

Silence

Zero on every channel for the whole run.

Constant(f32)

Constant DC: every sample is value on every channel.

Buffer(Vec<Vec<f32>>)

Channel-major buffer (bufs[ch][frame]). Length must be >= total_frames; shorter buffers panic at run-time. The channel count must match the driver’s channels.

Generator(Box<dyn FnMut(usize, f64) -> f32>)

(frame_idx, sample_rate) -> sample. Same value goes into every channel. Useful for sweeps / noise / generators.

Trait Implementations

impl Default for InputSource

fn default() -> InputSource

Returns the “default value” for a type.
