Crate sim_lib_plugin_vst3 

VST3-shaped plugin export adapters for SIM audio graph processors.

Modeled tier, no native hosting. This crate is a pure-Rust, in-process MODEL of the VST3 plugin format: the workspace forbids unsafe and the crate carries no -sys/FFI dependency, so export_*_as_vst3 produces descriptors, not native .vst3 binaries, and no plugin loading occurs. Native export and hosting are deferred; current_vst3_scope names the blockers and SDK requirements. The modeled tier is flagged by the default-on model feature.

use sim_lib_plugin_vst3::vst3_gain_vst3_descriptor;

let vst3 = vst3_gain_vst3_descriptor().unwrap();
assert_eq!(vst3.buses.len(), 3);

let descriptor = vst3.to_plugin_descriptor().unwrap();
assert_eq!(descriptor.id.format.as_str(), "vst3");
