Trait Plugin 

pub trait Plugin: Send + Sync {
    // Required methods
    fn metadata(&self) -> &PluginMetadata;
    fn instantiate(&self) -> Box<dyn AudioNode>;
}

Host-side abstraction over a loaded plugin.

Plugin is the trait the host calls after the ABI check passes. The loader’s own implementation ([HostPlugin]) bridges the plugin’s extern "C" entry symbols to this trait, but consumers that build their own plugin adapters (e.g. for in-process test plugins) may implement it directly.

Send + Sync is required so a PluginLoader can be moved between setup threads; instantiation produces a Box<dyn AudioNode> (which is only Send) for the single RT thread.

Required Methods

fn metadata(&self) -> &PluginMetadata

Static identity of this plugin (name, version, description, …).

fn instantiate(&self) -> Box<dyn AudioNode>

Construct a fresh audio-node instance backed by this plugin.

Each call yields an independent Box<dyn AudioNode> whose lifetime is bounded by the caller; dropping it releases the opaque handle (when the plugin exposes audio_plugin_destroy).

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
