Struct PluginLoader 

pub struct PluginLoader { /* private fields */ }

Discovers and loads plugins from a directory.

For each .toml manifest found, discover_and_load checks whether a corresponding native library (.so/.dylib/.dll) or WASM module (.wasm) exists alongside it. Native library loading requires unsafe FFI and is left as a stub — the manifest is still returned so callers can inspect what was found.

Implementations

impl PluginLoader

pub fn new(plugin_dir: &Path) -> Self

Create a new loader pointing at plugin_dir.

pub fn discover_and_load(&mut self) -> Result<Vec<PluginManifest>>

Scan plugin_dir for .toml manifest files, resolve the binary path, and return the manifests found.

Native library loading (dlopen / WASM runtime) is intentionally stubbed out — this method only reads manifests and resolves paths.

pub fn get_stages(&self) -> Vec<Box<dyn CompressionStage>>

Return CompressionStage wrappers for every loaded plugin, sorted by ascending priority.

pub fn register(&mut self, plugin: Box<dyn SqzPlugin>, config: Value)

Register a native plugin directly (used in tests and by callers that construct plugins programmatically).
