Crate bbx_plugin 

BBX Plugin

Plugin integration crate for the bbx_audio DSP library with C FFI bindings.

This crate re-exports the bbx_dsp crate and provides a macro-based API for generating C-compatible FFI functions from any PluginDsp implementation. Consumers only need to add bbx_plugin as a dependency to access both DSP functionality and FFI generation.

Example

use bbx_plugin::{PluginDsp, DspContext, bbx_plugin_ffi};

pub struct PluginGraph { /* DSP blocks */ }

impl PluginDsp for PluginGraph {
    fn new() -> Self { /* ... */ }
    fn prepare(&mut self, context: &DspContext) { /* ... */ }
    fn reset(&mut self) { /* ... */ }
    fn apply_parameters(&mut self, params: &[f32]) { /* ... */ }
    fn process(&mut self, inputs: &[&[f32]], outputs: &mut [&mut [f32]], midi_events: &[MidiEvent], context: &DspContext) { /* ... */ }
}

impl Default for PluginGraph {
    fn default() -> Self { Self::new() }
}

// Generate all FFI exports
bbx_plugin_ffi!(PluginGraph);
