Struct BusLayout 

pub struct BusLayout {
    pub inputs: SmallVec<[Bus; 2]>,
    pub outputs: SmallVec<[Bus; 2]>,
}

One complete I/O topology the plugin supports.

Hosts iterate over a plugin’s declared layouts and pick one before activation. After activation the layout is fixed until crate::PluginCore::deactivate is called.

Fields

inputs: SmallVec<[Bus; 2]>

Input buses in declaration order. Index 0 is the main input (when present); later indices are sidechains / auxiliaries.

outputs: SmallVec<[Bus; 2]>

Output buses in declaration order. Index 0 is the main output; later indices are auxiliaries.

Implementations

impl BusLayout

pub fn new() -> Self

An empty layout — no audio buses. Useful for MIDI-only plugins.

pub fn mono() -> Self

Mono-in, mono-out, no sidechains. The simplest effect layout.

pub fn stereo() -> Self

Stereo-in, stereo-out, no sidechains.

pub fn stereo_with_sidechain(sidechain_name: &str) -> Self

Stereo + sidechain input, stereo output. Compressors, gates, vocoders.

pub fn total_input_channels(&self) -> u32

Total input channels across every bus.

pub fn total_output_channels(&self) -> u32

Total output channels across every bus.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BusLayout

fn fmt(&self, f: &mut Formatter<'_>) -> Result

impl Default for BusLayout

fn default() -> Self

Returns the “default value” for a type.
