macro_rules! forward_plugin_instance {
($ty:ident) => { ... };
}Expand description
Implement PluginInstance for a $ty<P> newtype whose only relevant field
is inner: ProcessorPlugin<P>, forwarding all six methods to it. The clap,
lv2, and vst3 exported-processor adapters shared this forward block verbatim
before OVERLAP6.15. Call it at each adapter, where Processor, ProcessBlock,
and PrepareConfig (from sim_lib_audio_graph_core) and the plugin-core
trait types are already in scope.
