Struct PluginRunner 

pub struct PluginRunner { /* private fields */ }

Holds compiled plugin modules and runs them per-request.

Created at config publish time from the gateway’s plugins list. Cheap to clone (Arc internals). Each route’s plugins field names the plugins to run; the proxy pipeline calls the runner’s phase methods with those names.

Implementations

impl PluginRunner

pub fn new( plugins: &[PluginConfig], resolved: &HashMap<String, PathBuf>, ) -> Result<Self, String>

Build a runner from the gateway’s plugins list, compiling each WASM plugin’s module. A local plugin loads from its wasm: path; a registry source: plugin (DW-165) has no wasm field and loads from its resolved, verified artifact path in resolved (see crate::wasm::source). Plugins that fail to compile are skipped (with a log warning); the gateway starts even if a plugin is broken.

pub fn instantiate(&self, plugin_names: &[String]) -> Option<PluginInstances>

Create per-request instances for all plugins named on a route. Returns None when no named plugin has a compiled module (the caller treats that as fail-closed unavailability when the route does reference WASM plugins — DW-157). A plugin whose module fails to instantiate is skipped here with a warn; the caller is expected to verify coverage via PluginInstances::contains.

pub fn is_empty(&self) -> bool

Whether any plugins are configured.

pub fn has(&self, name: &str) -> bool

Whether a compiled module exists for name (DW-157). The lifecycle manager uses this at load time to mark plugins whose .wasm failed to read or compile as crashed (fail-closed), instead of leaving them reading as healthy with no module behind them.

Trait Implementations

impl Clone for PluginRunner

fn clone(&self) -> PluginRunner

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
